A permanent magnet has magnetic field lines as shown below. A wire carries a current vertically upward. The direction of the magnetic force on this wire at point C is best represented by

Two long, parallel wires separated by a distance d carry currents in opposite directions. If the left-hand wire carries a current i/2 and the right-hand wire carries a current i, determine where the magnetic field is zero.

A proton moves perpendicular to the magnetic field of 0.5 T. The track is observed to be a circular arc of radius 2.0 cm. Find: a) The direction of the force acting on the proton? b) The velocity of the proton c) The kinetic energy of the moving proton d) The magnitude of the force acting on the proton

In this image, the charged particle is moving to the right. The X's represent the direction of the magnetic field, B. Which direction will the force be on the charged particle? Remember, the direction your palm faces is the direction of the force. The direction the particle moves is I, or current. the force is up the force is down the force is to the right the force is to the left Maynetic Field B メ メメ メ positu Charge er turrent メXX O O

A long straight wire carries 4 A along the +x axis. Find the magnitude and direction of the magnetic field at a point that is 20 cm above the wire.

A long, straight wire carries a current. There is a uniform magnetic field directed downward (not due to the wire) and the force exerted on the wire is directed to the left. In what direction is the current?

A proton is moving to the right above a horizontal wire that carries a current to the right. What is the direction of the magnetic force on the proton?

A positive charge moving with a constant velocity v enters a region of a uniform magnetic field pointing upward. What is the direction of the magnetic force on the charge?

A particle that has an 8.6-μC charge moves with a velocity of magnitude 4.8 × 105 m/s along the +x axis. The maximum possible magnetic force that the charge with the given speed could experience has a magnitude of 0.577 N. Find the magnitude of the magnetic field

Which describes the net force on a magnetic dipole in a uniform magnetic field? The net force vector is in the direction of the magnetic field. O The net force vector is in the direction opposite that of the magnetic field. The net force vector is perpendicular to the direction of the magnetic field. O The net force vector is zero.
