Question 1 - Spiralling particle
A uniform magnetic field is directed into the page. A charged particle, moving in the plane of the page, follows a clockwise spiral of decreasing radius as shown. Using the formula r=mv/Bq, a reasonable explanation is...

Question 2 - Magnetic field of a rod
A current runs through a horizontally oriented wire toward the right of the screen. What type of field is generated and what is the direction of the current as viewed from the left end side of the wire?

Question 3 - Loop of wire
Label the magnetic field produced by the current carrying loop at the top, bottom, and opposite sides of the loop.

Question 4 - Rod on a table
A rod is placed lengthwise, horizontally, on a frictionless table permeated by a magnetic field directed upwards, with an electron flow towards the north. What direction does the rod move in?
