Which of the following is FALSE?    A current-carrying conductor has a magnetic field around it. A charge is not affected by the magnetic field if its velocity is zero. The right-hand source rule is a way of finding the magnetic field’s direction in a current-carrying conductor. A maximum magnetic force is obtained when the angle between the velocity of the charge and the magnetic is 180

PROBLEM SOLVING: SHOULD INCLUDE THE FOLLOWING: GIVEN, FORMULA, COMPLETE SOLUTION WITH UNIT ANALYSIS. 1. Magnetic force on a proton. A magnetic field exerts a force of 9 X 10-10 N toward the west on a proton moving vertically upward at a speed of 5 X 106 m/s. Determine the magnitude of the magnetic field. 2. A 2.50-m segment of wire supplying current to the motor of a submerged submarine carries 1000 A and feels a 4.00-N repulsive force from a parallel wire 5.00 cm away. What is the direction and magnitude of the current in the other wire? 3. A proton moves at 7.50 m/s perpendicular to a magnetic field.The field causes the proton to travel in a circular path of radius 0.800 m. What is the field strength?

A particle of mass 6.6 x 10 kg and charge +9.0 µC is traveling due east. It enters perpendicularly a magnetic field whose magnitude is 4.5 T. After entering the field, the particle completes one-half of a circle and exits the field traveling due west. How much time does the particle spend in the magnetic field? Number Units

There is an electron moving to the right undeflected by both the electric field in between the plates and the magnetic field coming out of the page in between the plates. The magnetic field has a magnitude of 4.0 T and the electric field has a magnitude of 8 N/C. What is the speed of the electron
