A metal rod 0.95 $\mathrm{m}$ long moves with a speed of 2.4 $\mathrm{m} / \mathrm{s}$ perpendicular to a magnetic field. If the induced emf between the ends of the rod is $0.65 \mathrm{V},$ what is the strength of the magnetic field?

Key Concepts

Magnetic Field Strength

Magnetic field strength is a measure of the intensity of a magnetic field, typically expressed in teslas (T). It is a fundamental parameter in determining the magnitude of induced emf in moving conductors, as the induced voltage is directly proportional to the magnetic field strength when other factors like velocity and conductor length are constant.

Lorentz Force

The Lorentz force is the force experienced by charged particles moving in a magnetic field, causing their deflection. In a moving conductor, this force acts on electrons, driving a current and resulting in an induced voltage (emf). Understanding the Lorentz force is key to linking the mechanical motion of the conductor with the electrical phenomena observed.

Motional Electromotive Force (emf)

Motional emf is the voltage induced across a conductor moving through a magnetic field, caused by the separation of charges due to the magnetic force. It is calculated using the product of the magnetic field strength, the length of the conductor in the field, and the perpendicular component of its velocity, highlighting the direct relationship between these physical quantities.

Faraday's Law of Electromagnetic Induction

Faraday’s law explains that a change in the magnetic environment of a conductor induces an electromotive force (emf) within it. When a conductor moves in a magnetic field, the change in magnetic flux experienced by the conductor generates an emf, which is quantitatively described by the product of the magnetic field strength, the length of the conductor, and its velocity.
