Magnetic fields
... The direction of the magnetic force is given by the magnetic force right-hand rule (RHR), which states as follows. To find the direction of magnetic force on a positive charge, start by pointing the fingers of your right hand in the direction of the velocity, v. Now curl your fingers forward the dir ...

615-0335 (10-152) Lenz`s Law Pendulum
... gives the direction of the electromotive force caused by electromagnetic induction. Electromagnetic induction is a phenomenon caused when a magnetic field interacts with a conductive material. As the material passes through the magnetic field, electrons in the conductor become excited by the magnet. ...

Today: Oscilloscope and Faraday’s Law
... Last week we put a voltage on a coil of wire. The resulting current in the coil made it act like a magnet. In other words a current can produce an magnetic field – evidence that electricity and magnetism are connected. Q. Can a magnetic field produce a current? A. Yes… but it is not as easy. A const ...
