Question

0 A proton moves north with a speed of 20 x 10 mis. A 5.0 T magnetic field is directed west, what is the magnitude je magnetic force acting on the phonon? @ An election is moving at 3.0 X10 mis east ina magnetic field of D.IT directed into the page. What is the radius of the circular pam of the moving electron? 3 A current of 20.0 A flows east through a 50.0 cm Aung wire. A magnetic field of 4.0 I is directed into the page. What is the magnitude of the force acting on the wire? © A current of 30.0 A flows north on a 5.0m long wire and current Of 50.0A flows south on another 5.0m long wire. The two wires are 3.0 em apart. what is the magnitude of the magnetic force per unit length between two wires 5 A wire carries a current Df 10.0 A. At what distance twm the wire will a magnetic field of 8.0X10-4 T be produced? A circular Coil of 1000 turns nas a radius of 10.0 cm and carries a current Of 50.0 A. what is the magnetic field at the center of the coil?
