Determine the magnetic field b at the point p

Assignment Help Electrical Engineering
Reference no: EM13962403

A current I flows in the loop shown in Figure 1, which comprises a semicircular segment of radius a centred on point P and two straight-line segments, each of length (square root)2a. All three segments are made from the same kind of thin wire.

Determine the magnetic field B at the point P (You do not need to derive any formulae that you use for fields due to current elements with standard shapes).

The figure has got me stumped. How do I deal with the difference circular and square? Do we use Amperes law?
