Answer 1

Answer #1

Magnetic field and magnetic flux in the loop are reduced by half and so does the rate of change of flux.

Emf induced will be reduced to half.

Emf changes by a factor of 1/2.

An decreasing current I flows in an elliptical loop of wire. Two loops of wire are placed as shown. Why is the flow of induced current counterclockwise for loop 1? I thought that mutually induced emf equals (-)M(di/dt). Doesn't the negative sign mean that the mutually induced emf (and hence the induced current) will be in the opposite direction of the rate of change of current? So why wouldn't the induced current for loop 1 be clockwise? ALSO: what is...
