10 (Faraday's Law, quantitative: The figure below shows a loop 10 cm in diameter oriented in three different ways in a magnetic field. (In figure c the loop is seen edge-on.) The field's magnitude is changing steadily with time as indicated on the figure. The loop has a resistance of 0.10. For each situation (a, b, and c, determine the magnitude of the EMF induced in the loop, the current induced in the loop, and the direction of induced current flow. (a) B field (b) B field c B field magnitude magnitude magnitude increasing decreasing decreasing at 0.5 T/s at 0.5 T/s at 0.5 TVs

Explanation / Answer

Here ,

R = 0.10 Ohm

r = 10/2 cm = 5 cm

r = 0.05 m

a) dB/dt = 0.5 T/s

current in the loop = pi * r^2 * dB/dt /R

current in the loop = pi * 0.05^2 * 0.5/.1

current in the loop = 3.92 *10^-2 A

as the magnetic field is increasing

Using lenz's law

the direction of induced current is CLOCKWISE

b)

current in the loop = pi * r^2 * dB/dt /R

current in the loop = pi * 0.05^2 * 0.5/.1

current in the loop = 3.92 *10^-2 A

as the magnetic field is decreasing

Using lenz's law

the direction of induced current is CLOCKWISE

c)

current in the loop = Area * dB/dt /R

current in the loop = 0 * 0.5/.1

current in the loop = 0 A

as the magnetic field is increasing

Using lenz's law

the direction of induced current is NULL
