We move a square loop of wire 2.3 cm on a side into a region of uniform magnetic field of 1.5 t with the plane of the loop perpendicular to the direction of the field. the loop is moving with a constant velocity of 2.1 m/s into the field region starting from a point outside the field. if the loop has a resistance of 3 ω, find the force on the loop as it just enters the magnetic field region. (enter the magnitude.)

Force will be

Explanation:

We have given side of wire d = 2.3 cm = 0.023 m

Magnetic field B = 1.5 T

Velocity v = 2.1 m/sec

Resistance R = 3 ohm

We know that current is given by

Power is given by

We know that power is also given by

So

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
