2 coils A and B are rotated in a magnetic field of 2 T. Coil A is a circular coil of radius 7m and coil B is a separate square coil with each side of 16 m. At what frequency should the coil B be rotated such that both coil A and B have the same induced voltage given coil A is rotated at 75 MHz?

In this problem, you will use Lenz's law to explore what happens when an electromagnet is activated a short distance from a wire loop. You will need to use the right-hand rule to find the direction of the induced current. When the switch is open, which of the following statements about the magnetic flux through the wire loop is true? Assume that the direction of the vector area of the wire loop is to the right. There is no magnetic...

Procedure: Take one of the coils and connect it to the
galvanometer. Use the cylindrical magnet to generate a changing
magnetic field around the coil and note the reading of the
galvanometer as the field changes. Thrust the N pole of the magnet
into the coil and note the effect on the galvanometer. When the
needle has come to rest, withdraw the magnet as quickly as
possible. Note the effect on the direction of current flow. Reverse
the magnet and...

What is the relationship between the number of coils in a solenoid and the emf induced in it by a change in the magnetic flux through the solenoid? a. The induced emf is inversely proportional to the number of coils in a solenoid. b. The induced emf is directly proportional to the number of coils in a solenoid. c. The induced emf is inversely proportional to the square of the number of coils in a solenoid. d. The induced emf...

Helmholtz coils are frequently used in experiments because they
create a uniform magnetic field about their axial direction. For
example, they are traditionally used in the experiment for the
measurement of the charge to mass ration of the electron. Helmholts
coils are two coils separated by a distance equal to their radius
and also carry equal currents in the same direction, as shown in
the figure on the right. Supposed the radius of the coil is 15.00
cm, each coil...

A constant uniform magnetic field of 0.45 T is applied at right angles to the place of a flat rectangular loop with an area of 4.5 x 10^-3 m^2. If the area of this loop steadily changes from its original area to a new area of 2.5 x 10^-3 m^2 in 1.3s what is the emf induced in the loop?

A set of "Helmholtz" coils is a pair of identical coils, each having radius a, N turns, and current I. They are positioned a distance a apart with the axis of each coil on the x-axis. Each coil is parallel to the y-z plane, as shown. The origin is halfway between the coils. a) Determine the magnetic field magnitude and direction at any position x on the x-axis. b) Graph this magnetic field magnitude as a function of x, for...
