1) You decide to build a small generator by rotating a coiled wire inside a static magnetic field of 0.40 T. You construct the apparatus by coiling wire into 5 loops of radius 0.19 m. If the coils rotate at 2.0 revolutions per second and are connected to a device with 120Ω resistance, calculate the average power Paverage supplied to that device.

2) A 121‑turn circular coil of radius 2.99 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 16.1 Ω resistor to create a closed circuit. During a time interval of 0.183 s, the magnetic field strength decreases uniformly from 0.667 T to zero. Find the energy, in millijoules, that is dissipated in the resistor during this time interval.

Helmholtz coils are a method developed to provide a uniform magnetic field in a small region. They are constructed by placing two identical wire loops parallel to each other, separated by a distance equal to their radii, as shown in the Figure. Assume that the two loops are also connected in parallel to a power supply, so that they produce the same field. (a) Find the length of a 28-gauge copper wire that will produce a 75 Ω coil. m...

Written Problem: Induction from a falling magnet We have a small magnet with a magnetic moment of m = 0.1 Am2 (remember: magnetic moment is defined as m = IA - see page 932 of book for the definition). We also have coils of wire. The coils are made out of 100 circular loops of a single wire. A single loop has a radius of 10 cm. The thickness of the wire has a circular cross section with a 0.5...

An electric generator is designed to produce a maximum emf of 220 V while rotating with an angular speed of 3600 rpm. Each coil of the generator has an area of 0.027 m2. a.) If the magnetic field used in the generator has a magnitude of 0.050 T, how many turns of wire are needed? b.) During the rotation of the coils, the magnetic flux through the coils will alternately be increasing and decreasing. (Why?) While the flux is increasing,...
