Question An electron moving with a speed of 2.7 x 105 m/s in the negative y direction experiences zero magnetic force. When it moves in the negative x direction, it experiences a force of 6.2 x 10-¹2 N that points in the positive z direction. What are the direction and magnitude of the magnetic field? You may specify the direction of the magnetic field either with unit vectors; x-hat, y-hat, or z-hat (i, j, k is fine too); or by drawing a vector in the coordinate system drawn below. 14

In 1962 measurements of the magnetic field of a large tornado were made at the Geophysical Observatory in Tulsa, Oklahoma. If the magnitude of the tornado's field was B = 14.00 nT pointing north when the tornado was 9.40 km east of the observatory, what current was carried up or down the funnel of the tornado? Model the vortex as a long, straight wire carrying a current. A (conventional current) flowing the tornado. -Direction--- Additional Materials
173% NASA and the military have long been interested in so-called “rail guns" to launch projectiles and payloads at very high velocities. A schematic of a rail gun is shown below, where there are two parallel rails separated by a distance d and connected to a powerful battery of voltage V, in a constant magnetic field B = Bok pointing out of the page. The projectile / payload can be modeled as a bar of mass m and resistance R which connects the two rails and completes the circuit. Assume the electrical resistance of the rails is negligible, but take there to be a constant force of kinetic friction with magnitude ƒ between the bar and the rails. (a) What is the current in the circuit when the bar is moving with velocity v? Remember to account for both the battery and the induced EMF. (b) What is the net force on the bar when it is moving with velocity v? (c) Using Newton's second law, F = ma, find a differential equation relating and v. (d) Verify that the solution to your differential…
