... - In a conservative situation (no friction) – the amount work done gives the amount that PE, KE and PEspring switch forms between one another. - In Non-conservative situations (friction) – the amount of work done by friction gives the amount of ME removed. There is a loss in ME (PE+KE) and this loss ...

... Lenz’s law is used to determine the direction of this induced emf. Lenz’s law states that the magnetic field generated by the induced current opposes the change in the magnetic field that created the induced current. If the magnetic field of the magnet is increasing then the magnetic field generated ...

... 4. The figure shows a parallel plate capacitor and the current direction in the connecting wires. The plates are circular with a radius of R = 1 cm, and the current going into the plates is i = 4 A. What is the magnetic field (magnitude and direction) between the plates at the shown position P at a ...
