Use the right hand dynamo rule to predict which way the induced current flows through the conductor AB in diagrams (a) and (b) below (i) Diagram (a): Magnet stationary, conductor moves in the direction of the arrow. Induced current flows from (ii) Diagram (a): Magnet moves in the direction of the arrow, conductor stationary. Induced current flows from (iii) Diagram (b): Magnet stationary, conductor moves in the direction of the arrow. Induced current flows from (iv) Diagram (b): Magnet moves in the direction of the arrow, conductor stationary. Induced current flows from

Suppose that an electromagnetic wave which is linearly polarized along the x−axis is propagating in vacuum along the z−axis. the wave is incident on a conductor which is placed at z > 0 region of the space. the conductor has conductivity σ, magnetic permeability µ and electric permittivity ε. (a) find the characteristic time for the free charge density which dissipates at the conductor. (b) write the maxwell equations and derive the wave equation for a plane wave propagating in a conductor. (c) find the attenuation distance at which the incident amplitude reduces to e ^−1 of its initial value. (d) find the electric and magnetic fields inside the conductor. 8 (e) find the power loss per area of the incident electromagnetic wave at the surface of conductor.
