Current balance/ force acting on a current-carrying conductor with an amperemeter

Product No: P2410601

Principle

The force acting on a current-carrying conductor loop in a uniform magnetic field (Lorentz force) is measured with a balance. Conductor loops of various sizes are suspended in turn from the balance, and the Lorentz force is determined as a function of the current and magnetic induction. The uniform magnetic field is generated by an electromagnet. The magnetic induction can be varied with the coil current.

Tasks

The direction of the force is to be determined as a function of the current and the direction of the magnetic field.
The force F is to be measured, as a function of the current IL in the conductor loop, with a constant magnetic induction B and for conductor loops of various sizes. The magnetic induction is to be calculated.
The force F is to be measured, as a function of the coil current IM, for a conductor loop. In the range being considered, the magnetic induction B is, with sufficient accuray, proportional to the coil current IM.
