The magnetic field from the center of a current-carrying wire
is,
B = (o
* I / (2
* r)
Where
o is the vacuum permeability, I is the current and r is the
distance from the wire.
----------------------------------------------------
Substituting values,
B = (4
* 10-7 * 75) / (2
* 3 * 10-2)
= 5.00 * 10-4 T (option B)
