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 ...

Researchers have recently discovered a mechanism that allows a concentrated laser beam to alter the magnetic state of a solid material. This breakthrough could revolutionize ultrafast computer memory.

can be recast in the same form as a basic mathematical formula that governs the behavior of electric currents and magnetic fields. This work can help make new concepts more understandable by ...
