Calculate the magnitude of the magnetic force exerted on a wire that is 20 mm long and carries a current of 4.0 a when it is suspended inside a solenoid at an angle of 45∘ to the magnetic field. the solenoid has 600 turns per meter of length and carries a current of 3.0 a .

Explanation:

We have given

Length of wire  l=20 mm=

Current carried by solenoid i =3 A

Number of turns n = 600 turns per meter

Magnetic field inside a solenoid is given by

Current carried by the wire = 4 A

The wire is suspended at an angle of 45° so

Now force on the wire

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary
