Very long wire, current 5A after t = 0
A current of 5 Amps is switched on in 1 ms at time t = 0 in a very long wire. A wire loop of
dimension 20 by 10 cm is located distance 10 cm from the wire. What Emf V1 is induced in
the loop at time zero if
a) (i) the loop is “parallel to the wire or (ii) what is V2 if it is perpendicular to the wire?|
b) What direction would the induced currents flow if the loops were closed?
c) What would the Emf be if the current was then switched off again after a long delay?
