    Given Information:

    Diameter of solenoid = 5.0 cm

    Magnetic field = B = 2.0 T

    Rate of change of magnetic field = 3.0 T/s

    Required Information:

    Electric field strength inside the solenoid at a point on the axis = ?

    Answer:

    The electric field strength inside the solenoid at a point on the axis is zero.

    Explanation:

    From the Faraday’s Law

    E = -r/2 dB/dt

    Where dB/dt is the rate of change of magnetic field and r is zero because the distance from the axis is zero.

    Therefore, electric field strength inside the solenoid at a point on the axis is 0.
