4. Protons are trapped by the Earth's magnetic field in the Van Ellen belt 40,000 miles above. The protons have a KE of 100Mey and their velocity makes an angle of 530 with the magnetic field of the earth whose value is 10-5 T. a) Find the velocity of these protons and their components parallel and transverse to the field,...

A power line carries a 500-A current towards magnetic north and is suspended 10 m above the ground. The horizontal component of earth’s magnetic field at the power line’s latitude is 24 T. If a magnetic compass is placed on the ground directly below the power line which direction will it point? In this question, I understand why how to...

A long solenoid has a diameter of 12.0 cm. When a current i exists in its windings, a uniform magnetic field B = 27.0 mT is produced in its interior. By decreasing i, the field is caused to decrease at the rate of 5.50 mT/s. Calculate the magnitude of the induced electric field at the following distances from the axis...
