WebJul 6, 2024 · Magnetic field sources are dipolar, meaning they have a north and south pole. And when it comes to magnets, opposite poles (N and S) attract while other poles (N and N, S and S) repel. WebSep 12, 2024 · The magnetic field lines are shaped as shown in Figure 12.5.2. Notice that one field line follows the axis of the loop. This is the field line we just found. Also, very close to the wire, the field lines are almost circular, like the lines of a long straight wire.

WebMagnetic field sources are essentially dipolar in nature, having a north and south magnetic pole. The SI unit for magnetic field is the Tesla, which can be seen from the magnetic part of the Lorentz force law F magnetic = qvB to be composed of (Newton x second)/(Coulomb x meter). A smaller magnetic field unit is the Gauss (1 Tesla = 10,000 Gauss). WebMay 25, 2024 · Amplifying magnetic fields — the dynamo effect. Scientists started thinking about this problem by considering the way that electric and magnetic fields were produced in the laboratory. When conductors, like copper wire, move in magnetic fields, electric fields are created. These fields, or voltages, can then drive electrical currents.
