CHAPTER – 14 Electric current and its Effects
... Switch on the current. After a few seconds touch the wire. The wire feels hot. Then switch off the current. After a few seconds touch the wire again. It does not feel hot. This shows that when electric current flows through a wire, it Nichrome wire gets heated. Nail ...

EM-3 Powerpoint (Scannell)
... segment of wire .040 m long is perpendicular to the magnetic field inside a solenoid. When a current of 3.0 amps flows through the wire, it takes a force of 0.020 Newtons to balance the wire. What is the magnetic field inside the solenoid. ...

The Lorentz force law and the magnetic field
... It turns out to be more appropriate to treat the current as a current density vector rather than a simple current scalar, I, since the current may vary in both direction and magnitude from place to place. The current density captures both of these features. A current I may be viewed as made up of ma ...
