Magnetic Fields & Magnetic Field Strength
... • We have seen that magnets can exert a force on objects without touching them. For this reason we speak of a magnetic field around a magnet, in the same way that we speak of an electric field around a charged object. ...

For a long straight wire B = ( ìo I )/ ( 2 ð r) ìo = 4 ð x 10-7
... Recall that we first used Coulomb’s Law to calculate the electric force. Then we used F = qE and found the value of E by using Gauss’ Law. As we saw in the last chapter with F = qvB, if the magnetic field is known then we can easily calculate the magnetic force. Ampere’s Law helps us to find the mag ...
