The strength of the magnetic field of earth at its surface is roughly 0.5 t (tessa) or 5 x 10^-3 t. on the other hand, magnetic resonance imagining (mri) requires a magnetic field of about one tesla. calculate the strength of the magnetic field at three distances (0.5 cm, 1.0 cm, and 1.5 can) from a straight vertical current-carrying wire with 3 a flowing through it. at approximately what distance does the magnetic field of the wire have the same strength as the magnetic field of earth?
