PDF Force on a square loop of current in a uniform B-field. Use Ampere's Law to derive that inside a wire with a uniform current distribution, B(r) is proportional to r. Recall the case of the electric field E(r) inside a wire with a uniform charge distribution: E(r) is also proportional to r. Outside a long, straight wire, both E and B as proportional to 1/r. 10.2 Magnetic field associated with a current - Siyavula A solenoid is a cylindrical coil of wire acting as a magnet when an electric current flows through the wire. The magnetic field pattern around a solenoid is similar to the magnetic field pattern around the bar magnet that you studied in Grade 10, which had a definite north and south pole as shown in Figure 10.3 . How to determine the direction of induced current flow? The current in the loop is such that it would create this induced field according to the usual right-hand rule for B-fields due to loops. So imagine that the B-field was decreasing instead. So if B is up the change in the B-field is down. Thus the induced B-field would point up and the current would be opposite to what is in the diagram. Essay Fountain - Custom Essay Writing Service - 24/7 ... It is very easy.

Lenz's Law - University Physics Volume 2 Lenz's Law. The direction of the induced emf drives current around a wire loop to always oppose the change in magnetic flux that causes the emf. Lenz's law can also be considered in terms of conservation of energy. If pushing a magnet into a coil causes current, the energy in that current must have come from somewhere.
