The magnetic field of a cylindrecal magnet that has a pole `-` face radius `2.8 cm` can be varied sinusoidally between minimum value `16.8 T` and maximum value `17.2 T` at a frequecy of `(60)/(pi) Hz`. Cross section of the magnetic field created by the magnet is shown. At a radial distance of `2 cm` from the axis find the amplitude of the electric field (in `m N//C` ) induced by the magnetic field variation.

The magnetic field of a cyclindrical magnet that has a pole face radius 2.8 cm can be varied sinusoidally between the minimum value 16.8 T and the maximum value 17.2 T at a frequency of 50//piHz . Cross section of the magneic field created by the nagnet is shown in Fig. 3.211. At a radial distance of 2cm from the axis, find the amplitude of the electric field (in units of xx 10^(2) mNC^(-1)) induced by the magnetic field variation.

The magnetic field of a cylindrical magnet that has a poleface diameter of 3.3 cm can be varied sinusoidally between 29.6 T and 31.2 T at a frequency of 15 Hz. (The current in a wire wrapped around a permanent magnet is varied to give this variation in the net field.) At a radial distance of 1.6 cm, what is the amplitude of the electric field induced by the variation?

The magnetic field due to a short magnet at a point in its axis at distance X cm from the middle of the magnet is
