Along solenoid, of radius a, is driven by an alternating current, so that the field inside is sinusoidal: b(t) b cos(ot)ż. a circular loop of wire, of radius a/2 and resistance r, is placed inside the solenoid, and coaxial with it. find the current induced in the loop, as a function of time. 6.

The current induced in the loop is .

Explanation:

Given that,

Magnetic field

Radius

Resistance =R

We need to calculate the area of the loop

Using formula of area

Put the value of r in to the formula

We need to calculate the flux

Using formula of flux

We need to calculate the emf

Using formula of emf

We need to calculate the current

Using formula of current

Hence, The current induced in the loop is .

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.
