This can interact with another magnetic field, causing a force that pushes the wire at right angles. This is called the motor effect. Figure caption, There is a force at right angles to the ...

To calculate the force on a wire carrying a current at right angles to a magnetic field, use the equation: 2 A flows through a 50 cm wire. Calculate the force acting on the wire when it is placed ...

And while this magnetic levitation motor does not break the laws of thermodynamics, it can be considered a perpetual motion machine, at least for certain values of perpetuity. The motor that ...

Permanent magnet is an object made up of ferromagnetic material, which has magnetic properties and creates its own magnetic field. Permanent magnet motors are manufactured using permanent magnets in ...

When an electric current passes through a metal wire, a magnetic field forms around that wire (see diagram at right). Likewise, a wire passing through a magnetic field creates an electric current ...
