Factors that Affect the Strength of the Electromagnet Aim:
To investigate factors which affect the strength of the electromagnet
and make the strongest electromagnet possible.
Apparatus:
· Iron Rod
· Leads
· Power Pack
· Crocodile Clips
· Insulated Wire
· Iron Nails
· Voltmeter
· Plastic Beakers
· Electronic Balance
Hypothesis:
I expect the strongest electromagnet to have a 'soft' iron core; the
highest number of coils (45); the strongest voltage (10V) and current
and have the coils evenly spread across the iron rod.
The 'soft' iron core means it changes easily between being magnetised
and de-magnetised, it is perfect for electromagnets, which need to be
turned on and off. From a previous experiment, using an electromagnet,
I found out that the iron rod picked up many nails when turned on and
dropped them all when switched off but the steel rod picked few nails
up when switched on, yet held on to them even after the current was
switched off. For this experiment, the iron rod is needed. A high
number of coils provides a stronger solenoid. When current flows
through the wires it create a magnetic field, therefore with more
coils a stronger magnetic field and therefore a stronger electromagnet
would be created. A stronger magnetic field will also be created if
the size of the voltage increases, the higher the voltage means the
size of current will increase too. The stronger the magnetic field,
In the twentieth century the medical field has seen many changes. One way that hospitals and nursing specifically has changed and implemented the changes is by pursuing accreditations, awards, and recognitions. The purpose of this paper is to understand Magnet Status and the change required by hospitals to achieve it.
For hospitals to reach their peak in the healthcare world they must work to achieve a prestigious credential by the American Nurse's Credentialing Center ( Truth about nursing). In order to receive such a credential, hospitals must fulfill a set of criteria that will take a lot of work and reform within the hospital itself. To receive magnet status hospitals have to express the fourteen forces of magnetism along with the strict list of requirements (Flores, 2007). Magnet status along with everything has its benefits along with its problems. This credential has been researched in depth, and some research feels that certain thing should be changed in order for magnet hospitals to be the best they can possible be. Lastly, there is no doubt that magnet status is of great value because of how it transforms hospitals from great to greater.
training. Improve work environment also contributes to financial benefits with lower injuries to nurses such as needle sticks and back injuries. Magnet organizations have to outperform national benchmarks on nurse sensitive indicators such as falls, hospital acquired pressure ulcers, central line associated blood stream infection, catheter associated urinary tract infections, and ventilator associated pneumonia, to achieve Magnet designation and to maintain it. Decrease in hospital acquire preventable incidences equates to less rejected insurance reimbursement.
Electromagnetism is creating a revolution aboard U.S. Navy ships. First the navy unveiled its first gun that utilizes this energy to accelerate projectiles earlier this year. By using electromagnetic energy, the project can be accelerated to higher speeds than a bullet in a conventional gun. It can also fire such projectiles over an impressive 100 nautical miles. Such weaponry marks the first true advancement in the actual method used to accelerate project weapons since the earliest form of primitive muskets. Certainly the speed of fire and loading of guns increased incredibly over the past century and more, but they always relied on a chemical explosion to accelerate the projectile down the barrel.
An increase in the number of coils applied to the iron nail will cause an increase in the number of paperclips being picked up. (a positive correlation between the two variables). This prediction is derived from the scientific knowledge above. Therefore, the more turns of the coil you have, the greater the. magnetic field and the stronger the electromagnet. Apparatus: -.
doubled the chances of getting cancer. This test was conducted by the National Cancer Institute (NCI), it also showed that electrical workers are at three times the risk of contracting cancer.
of the atoms, so if there are more or larger atoms then there must be
Factors Affecting the Resistance of a Wire The aim of this experiment is to investigate one factor that affect the resistance of a wire. I will do this by performing an experiment. First I will need to identify the factors that effect resistance. There are a few factors that affect the resistance, it is determined by the properties an object has.
Allow the nails to dry for 15 minutes. Once they become hard you can file
By adding up to 2%,of carbon it makes the steel tough and strong. Although it’s tough and strong, it is able to bend. To make sure that the metal doesn’t rust, it has a zinc coating on it. Iron is 26 on the periodic table,and considered an “transition metal,” meaning that it is ductile and malleable, and conduct electricity and heat. ... “Some other elements that are similar to iron are cobalt and nickel. They are the only elements known to produce a magnetic field.” Zinc is 30 on the periodic table and it is also a transition metal like iron. “The first iron used by humans is likely to have come from meteorites.” A meteorite is a meteor that survives its passage through the earth's atmosphere such that part of it strikes the ground. More than 90 percent of meteorites are of rock, while the remainder consist wholly or partly of iron and nickel. Meteors are believed to have been from the asteroid belt of Mars and
The Physics of an Electric Motor An electric motor is a device used to convert electric energy into rotational kinetic energy. There are two different types of electric motors, and each has its own use. The different types are direct current and alternating current motors. Each of these motors will be analyzed in the following steps.
A lot of things trigger my nail bitting, but two of the biggest for me are stress and boredom. When I’m stressed out, bitting my nails
Magnets are stones that produce magnetic fields. The magnetic field is invisible, but is responsible for the most noticeable aspect of a magnet: the attraction of a metal object or the repulsion of another magnet. Magnets are used in common everyday household items: credit cards, TVs, speakers, motors, and compasses. A magnets strength is measured by its magnetic moment. (“Magnetism”)
Temperature has a large effect on particles. Heat makes particles energized causing them to spread out and bounce around. Inversely the cold causes particles to clump together and become denser. These changes greatly F magnetic the state of substances and can also influence the strength of magnetic fields. This is because it can alter the flow of electrons through the magnet.
The Earth’s magnetic field is a major component to exploring the earth. The north and the south poles have always been a guide for travelers. Using compasses, the direction of the north pole and the south pole has always been provided by the magnetic force of the magnetic field. What many people do not know though is the earth’s magnetic field provides way more than that. The magnetic field, also known as the magnetosphere, protects us from all kinds of harmful substances. Some of these substances include solar wind and harmful radiation from the sun. The magnetosphere also protects the atmosphere, which protects us.
