Understanding Magnetic Fields

What does a magnetic field indicate?

• The color of a magnet

• The direction of the south pole of a magnet

• The strength of a magnet

• The direction of the north pole of a magnet

What is the unit of the magnetic field?

• Tesla

• Joule

• Newton

• Watt

Which equation is used for a single charged particle in a magnetic field?

• Ohm's Law

• Newton's Second Law

• Equation for a single charged particle

• Equation for a current-carrying wire

What is the angle theta in the context of magnetic fields?

• The angle between the velocity and the magnetic field

• The angle between the magnetic field and the ground

• The angle between the current and the electric field

• The angle between two magnetic fields

When is the force from a magnetic field on a moving charge at its maximum?

• When the charge moves in a circular path

• When the charge is stationary

• When the charge moves parallel to the field

• When the charge moves perpendicular to the field
