Question

Which situation defines a magnetic field of 1 tesla?

Options

• A charge of 1 coulomb moving at 1 m/s parallel to the field experiences a force of 1 newton.

• A charge of 1 coulomb moving at 1 m/s at right angles to the field experiences a force of 1 newton.

• A charge of 1 coulomb at rest experiences a force of 1 newton.

• A charge of 1 coulomb moving at 1 m/s at right angles to the field experiences no magnetic force.

Answer 1

The definition uses a 1-coulomb charge moving at 1 m/s at right angles to the field. In a field of 1 tesla, that charge experiences a magnetic force of 1 newton.
