Which direction will the force be on a proton moving left at location ?

A piece of metal has a motional emf of is moving through a magnetic field going into the page (depicted by the x's) with a magnitude of . The length of the metal piece (vertical length as opposed to horizontal length) is . Find the magnitude of the velocity of the object.

An positively charged object moving west on the equator experiences a magnetic force pointing up to the sky. What is the direction of the dominant magnetic field at this location?

An electron at location is moving to the right. What will be the direction of the magnetic force?

Electrons are rotating counter-clockwise in the plane of the screen. What is the direction of the magnetic field at the center of rotation created by these electrons?

Suppose that an electron is accelerating outward, within the plane of the page, in a counter-clockwise direction as shown in the picture below. In what direction would a magnetic field need to be pointing in order to cause the electron to move in this way?

Suppose that an electron is traveling due east while in the presence of a magnetic field that is oriented such that it is pointing outward, away from the viewer. In what direction does the magnetic force on this electron point?

An electron is traveling into a screen at the same time another electron is traveling out of the screen. They are far enough away to not collide with each other. Will the magnetic forces between them be attractive or repulsive?
