What creates a magnetic Hold? More than one answer may be correct, (a) a stationary object with electric charge (b) a moving object with electric charge (c) a stationary conductor carrying electric current (d) a difference in electric potential (e) a charged capacitor disconnected from a battery and at rest Note: In Chapter 34, we will see that a changing electric field also creates a magnetic field.

A Hall probe gives a reading of 1.5V for a current of 2 A when it is placed in a magnetic field of 1 T, What is tire magnetic field in a region where tire reading is 2V for 1.7 A of current?

If a cosmic ray proton approaches the Earth from outer space along a line toward the center of the Earth that lies in the plane of the equator, in what direction will it be deflected by the Earth’s magnetic field? What about an electron? A neutron?

An electron moving along the +x -axis at 5.0106m/s enters a magnetic field that makes a 75° angle with the x-axis of magnitude 0,20 T. Calculate the (a) pitch and (b) radius of tire trajectory.

If you cut a bar magnet into two pieces, will you end up with one magnet with an isolated north pole and another magnet with an isolated south pole? Explain your answer.

Why do iron filings show magnetic field patterns?

Discuss the similarities between the energy stored in the electric field of a charged capacitor and the energy stored in the magnetic field of a current-carrying coil.

The quantity B ds in Amperes law is called magnetic circulation. Figures 30.10 and 30.13 slum paths around which the magnetic circulation is evaluated. Each of these paths encloses an area. What is the magnetic flux through each area? Explain your answer.
