magnetic effects of electric current
... that the displacement of the rod is largest (or the magnitude of the force is the highest) when the direction of current is at right angles to the direction of the magnetic field. In such a condition we can use a simple rule to find the direction of the force on the conductor. In the above activity ...

... James Clark Maxwell (1831-1879) postulated a set of laws which define the relationship between the electric field E, the magnetic field H and the sources of these fields: ρ (volume density of free charges) and currents, J (surface density of free currents). These laws can be written in terms of the ...

... The magnetic field at the loop due to the long wire is into the page, and can be calculated by Eq. 28-1. The force on the segment of the loop closest to the wire is towards the wire, since the currents are in the same direction. The force on the segment of the loop farthest from the wire is away fro ...
