Electromagnetism Calculators. Electromagnetism is a branch of physics which involves the study of the electromagnetic forces. The electromagnetic force is one of the four known fundamental forces, which are a weak nuclear force, strong nuclear force, gravitational force and electromagnetic force.
This Faraday’s law calculator will help you find the electromotive force induced in a closed circuit. What is electromagnetic induction? If you attached a metal wire to a battery , you would create a current – electrons would move along the wire.
Electromagnetic induction is the production of an electromotive force across a conductor when it is exposed to a varying magnetic field. The induced electromotive force in any closed circuit is equal to the rate of change of the magnetic flux through the circuit.

Electromagnetic Induction Chapter 14 – Magnetism and Electromagnetism While Oersted’s surprising discovery of electromagnetism paved the way for more practical applications of electricity, it was Michael Faraday who gave us the key to the practical generation of electricity: electromagnetic induction.
Analyze your electromagnet to determine its dimensions and the amount of current you will be running through it. For example, imagine you have a magnet with 1,000 turns and a cross-sectional area of 0.5 neters that you will operate with 10 amperes of current, 1.5 meters from a piece of metal.

The magnetic force acting on a free electron in the rod will be directed upwards and has a magnitude equal to (32.1) Figure 32.1. Moving conductor in magnetic field.
Electromagnetic induction was discovered independently by Michael Faraday in 1831 and Joseph Henry in 1832. Faraday was the first to publish the results of his experiments. In Faraday’s first experimental demonstration of electromagnetic induction (August 29, 1831), he wrapped two wires around opposite sides of an iron ring (an arrangement similar to a modern toroidal transformer).

23 ELECTROMAGNETIC INDUCTION, AC CIRCUITS, AND ELECTRICAL TECHNOLOGIES Figure 23.1This wind turbine in the Thames Estuary in the UK is an example of induction at work. Wind pushes the blades of the turbine, spinning a shaft attached to magnets.
Faraday’s law is a fundamental relationship which comes from Maxwell’s equations. It serves as a succinct summary of the ways a voltage (or emf) may be generated by a changing magnetic environment. The induced emf in a coil is equal to the negative of the rate of change of magnetic flux times the number of turns in the coil.
Topic 12: Electromagnetic Induction . Lessons: Induced EMF: Faraday and Lenz’s Laws; PSOW: Eddy Currents and Lenz’s Law Electricity generators use the principle of electromagnetic induction. A simple generator is simply a coil of wire in a magnetic field. We can calculate the rms currents and voltages and then use them in circuit
