Along, straight wire with 5 a current flowing through it produces magnetic field strength 2 t at its surface. if the wire has a radius r, where within the wire is the field strength equal to 51 % of the field strength at the surface of the wire? assume that the current density is uniform throughout the wire. (μ 0 = 4π × 10-7 t · m/a)

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

elctricity and magnet is conversion to it
