INDUCTION

Apparatus for demonstrating the induced voltage in a frame coil that is moved through the magnetic field produced by a magnet plate of limited area or by the rotation of a current-carrying conductor in the magnetic field of the magnet plate ... more

The Electromagnetic Experiment Set offers a concise set-up for experiments in advanced topics of electricity and magnetism such as induction and paramagnetism. The product manual includes an in-depth look at these experiments topics: &bull ... more

Comprising a motor armature without an iron core, this device is intended for installation inside the permanent magnet with adjustable pole spacing (P 1002660 ). The coil is rotated purely by the Lorentz force, its direction of rotation ... more

Coils for experiments on induction in combination with the 120 mm diameter field coil (U12253) and for experiments on resonant electric circuits. The coils are only designed for safety extra low voltage (SELV). The spools are made of transparent ... more

600-winding coil without core attached to a safe box and featuring safety sockets. For experiments on induction, a bar magnet can be passed through the coil. Dimensions: 135x85x40 mm³ more

These Helmholtz coils are essential components for determining the specific charge of an electron (e/m) using a fine-beam tube (experiment 8000667 / 8000668). Additionally, in combination with the flat coil in a rotatable frame (item no: ... more

Flat coil in a plexiglas frame, mounted so that it can be rotated, for use in combination with 300 mm Helmholtz coils. When the flat coil is rotated in the magnetic field of the Helmholtz coils, an alternating voltage is induced. The electrical ... more

For the demonstration of the effects of eddy currents and braking. A pendulum object composed of a solid steel plate swings back and forth between the poles of an electromagnet with the power switched off. When the magnet is switched on, the ... more

No investigation into electromagnetic theory is complete without measuring the inductance and self-inductance of a current-carrying coil (depending on the insertion of an iron core) and exploring AC circuits. Our copper wire coil features ... more

Handy demonstration apparatus for illustrating Lenz’s law and induction of eddy currents. A small steel cylinder and a magnet of the same weight fall at different speeds through a copper tube because the motion of the magnet causes ... more

Guinea and feather tube apparatus with 6 induction coils connected in series. When a bar magnet (included in the scope of delivery) is dropped in the tube, a voltage is induced as it passes each of the respective coils. Due to the magnet ... more
