A 185‑turn circular coil of radius 3.79 cm and negligible resistance is immersed in a uniform magnetic field that is perpendicular to the plane of the coil. The coil is connected to a 14.5 Ω resistor to create a closed circuit. During a time interval of 0.147 s, the magnetic field strength decreases uniformly from 0.537 T to zero. Find the energy ? in millijoules that is dissipated in the resistor during this time interval.

In the figure, a wire loop of dimensions L= 42.3 cm and W = 26.5 cm lies in a magnetic field. What are the (a) magnitude 8 and (b) direction (clockwise or counterclockwise-or "none" if g = 0) of the emf induced in the loop if B = (5.40 x 102 T/m)yk? What are (c)8 and (d) the direction if B = (6.19 × 10-2 T/s)tk ? What are (e)g and (f) the direction if B - (8.18 x 10-2 T/m-s)ytk ? What are (g)g and (h) the direction if B (3.13x 10-2 T/m-s)xtj?

A flat coil of wire consisting of 15 turns, each with an area of 53 cm², is positioned perpendicularly to a uniform magnetic field that increases its magnitude at a constant rate from 3 T to 8 T in 3.4 s. If the coil has a total resistance of 0.3 ohms, what is the magnitude of the induced current in amperes?

The figure below displays a circular loop of metal wire in a uniform magnetic field pointing into the page. The radius of the loop is 15.0 cm and the magnitude of the field is 0.120 T.  You grab points A and B and pull them in opposite directions, stretching the loop until its area is nearly zero, taking a time of 0.210 s to do so. What is the magnitude of the average induced emf in the loop (in mV) during this time?
