A circular coil of radius 5 cm has 50 turns of wire. The uniform magnetic field directed into the page/screen (see the figure below) is linearly increased in magnitude form 0 to 0.8 T. What time interval for this increase is needed to induce in the coil emf = 0.25 V? What is the direction of the induced emf (clockwise/counterclockwise)? Which law do we use?

1) A 179‑turn circular coil of radius 3.55 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 13.7 Ω resistor to create a closed circuit. During a time interval of 0.121 s, the magnetic field strength decreases uniformly from 0.643 T to zero. Find the energy, in millijoules, that is dissipated in the resistor during this time interval. energy: mJ 2) You decide...
