You should feel a slight resistance when you try to push and pull the electromagnet into the coil. Where does this come from and what is the direction of this force? Why did it become harder to move the magnet into the coiled loop of wire as more wires were added, as you moved the magnet faster, or as the area of the loop was bigger?

Answer #1

Electromagnets are the magnets of the coil which produces an electromagnetic field when the current is allowed to pass through it Electromagnets are the current carrying conductors have their induced north and south poles Electromagnets are made up of a wire wound to form a coil or the added with the adjacent coil to obtain the total magnetic field. The upon the current induced in the coil and the total number of tums in the solenoid type. The magnetic field produced by each individual coil is magneto motive force produced by the electromagnets are depends col Now when an electromagnet is pushes away from the coil an electromotive force is induced as the number of magnetic flux crossing the electromagnet changes According to Faradays law the magnitude of the induced emf is equal to the time rate of change of magnetic flux through the circuit. The direction is determined using Flemings left hand rule states that the direction of the induced force is always perpendicular to the direction of current and the induced magnetic field The magnitude of this force is directly proportional to rate of change of magnetic flux. If the coil moves at the faster speed the magnitude of force is high and vice versa. Write the expression for the pull experienced by the coil. CAnlWhere, the area is A, the constant is C, the number of tums of the coil is n, the current flowing through the coil is I and the length of the coil is 1 It is clearly observed that the pull exerted by the electromagnet is directly proportional to the area of the coil and the number of tums. So the increase in the number of coils or increasing the area of the coil will induced a strong pull on the coil.
