I Review A Hall-effect probe to measure magnetic field strengths needs to be calibrated in a known magnetic field. Although it is not easy to do, magnetic fields can be precisely measured by measuring the cyclotron frequency of protons. A testing laboratory adjusts a magnetic field until the proton's cyclotron frequency is 9.80 MHz . At this field strength, the Hall voltage on the probe is 0.547 mV when the current through the probe is 0.141 mA . Later, when...

A loop of wire sits in a uniform magnetic field, everywhere
pointing toward you. Due to a changing magnetic flux through the
loop, an induced current flows in the wire, clockwise as shown. The
area of the loop is 1.94 m2, and the magnetic field initially has
magnitude 0.48 T.
(a) Suppose that, over a time period of 1.34 s, the magnetic
field changes from its initial value, producing an average induced
voltage of 8.0 V. What is the final...

Imagine that you can drive a current through a loop, creating a magnetic field, and that you can increase and de- crease the current at will. A changing magnetic field is associated with an elec- tric field, and in this problem I ask you to draw magnetic fields at two different times, and the associated electric field. The figure to the right shows the mag- netic field of the loop at t = 0 s. (View is from side.) --...

A magnetic field whose magnitude is B = 1.66 T impinges on a circular magnetic dipole of 100 turns, carrying a current of 3.33 A, whose radius isr= 2.66 cm. Because the magnetic dipole moment is rotated with respect to the field, the magnetic flux through the dipole is b = 2.64 x 10-3 Wb. (Wb is the abbreviation for 1 Weber = 1Txm2). What is the magnitude of the electric potential energy of the magnetic dipole in this field?
