How does the number of coils affect electromagnetism?
Hypothesis: When there is a flow of moving electrons, a magnetic field is created. We use the equation F = NIlB (Force = Number of coils x Current x Length of Wire x Magnetic Field Strength) to work out the magnetic force produced in a wire when there is an electric current present. Using this equation we can see that increasing the length of the wire (amount of coils) gives a larger force. So increasing the amount of coils in an electromagnet gives a larger EMF.
Variables-
Independent: Length of wire, Number of Coils in magnet
Dependent: EMF produced, Magnetic Field Strength, amount of coils in magnet.
Control: Volts, Amps, Ruler.
AIM – To find out how
Along with gravity and the strong and weak interactions (forces), the electromagnetic force is one of the four basic forces in the universe force. When a charged particle moves, it creates a magnetic field around its path of travel. This magnetic field moves with the charged particle along its path. This magnetic field is one of the key components of the equation F = NIlB, arguably the most important equation involving electromagnetism. B stands for the Magnetic Field Strength, so using a bit of common sense you can see that changing B will change the overall EMF (electromagnetic force). I will Explain I and l in a minute (that’s L)
We usually move electrons to do work, and when we move a lot of them, we create a large magnetic field around the conductor through which the electrons move. The moving electrons are electricity, and if we coil the conductor through which the current is flowing, we can cause the magnetic field around the individual wires to "add up" and make one bigger field. The bigger field "reaches around" the entire coil of wire, and the magnetic lines of force all flow through the center, and then out one end, around the coil in all directions, and then back into the other end. This is where l (L) and N come into play, increasing the length of the wire and the amount of coils means for a stronger EMF just like with changing the Magnetic Field
In AC, for each direction current flowed, a field would form, and then when the current changed direction, like it does in alternating current, that field would collapse and another one would form. This brings me to the last variable, I (even though it’s first in the equation) as you can probably guess, increasing the current flowing through the wire will increase the EMF as a larger current pushes more electrons through, creating more
