12.4 Exercise 1
Using the example, at what distance would you have to move the first coil to have zero measurable magnetic field at point P?
12.4 Exercise 3
What happens to the length of a suspended spring when a current passes through it?
12.4 Exercise 5
When the current through a circular loop is 6.0 A, the magnetic field at its center is What is the radius of the loop?
12.4 Exercise 7
A flat, circular loop has 20 turns. The radius of the loop is 10.0 cm and the current through the wire is 0.50 A. Determine the magnitude of the magnetic field at the center of the loop.
12.4 Exercise 9
Two flat, circular coils, each with a radius R and wound with N turns, are mounted along the same axis so that they are parallel a distance d apart. What is the magnetic field at the midpoint of the common axis if a current I flows in the same direction through each coil?
