Exercise 1
A 100 m cable wire carries a current of 30 A and it is perpendicular to the Earth’s magnetic field of 0.5x10-4 T. Find the magnitude of magnetic force on this cable.

Exercise 1
Determine the angle between a wire carrying an 8.00 A current and the 1.20 T magnetic field it is in if 50.0 cm of the wire experiences a magnetic force of 2.40 N?

4.
Exercise 1
Two parallel wires have a same currents and the magnitude of magnetic force between these wires is F. If the current in each wire is now doubled, determine the new magnetic force between these wires.

5.
Exercise 1
Two long parallel wires are separated at 0.20 m and carry currents of 20 A and 5.0 A in opposite directions. Determine the magnetic field at the middle of these wires.
