1. A metal with a 3+ charge travels at a speed 1000 m/s and is moving perpendicular to the magnetic field with a magnitude of 1.0 T. Determine the magnitude of magnetic force acting on the metal.
2. Determine the magnitude of Magnetic Force produced on a straight wire 50 cm long when a 20 A current flow on it while being exposed on a 20 T magnetic field acting 90° on the wire.
3. Determine the Current in a long straight wire that would produce a magnetic field that produce a Magnetic Field three times that of Earth's Magnetic Field located at a distance 10.0 cm from the wire. (Assuming Earth's Magnetic Field is equal to 5 * 10 - 5T & mu0=4 pi*10-7T.m/)
