Practice mode Electromagnetism

One tesla is the magnetic flux density in which ____.

Correct answer C. a 1 m wire carrying 1 A at right angles to the field experiences a force of 1 N

Explanation

From F = BIL sin θ with θ = 90°, B = 1 T when a force of 1 N acts on 1 m of wire carrying 1 A perpendicular to the field. A charge at rest feels no magnetic force.
