Question

Compute the magnitude of the field intensity due to a current of 8 amperes in a long straight wire at a distance five centimeters from the wire. The equation involved is H=2I/10r, where H is the magnitude field intensity (in oersteds), I is the current in the wire (in amperes), and r is the distance from the wire (in centimeters). Compute the magnitude of the field intensity due to a current of 8 amperes in a long straight wire at a distance five centimeters from the wire. The equation involved is H=2I/10r, where H is the magnitude field intensity (in oersteds), I is the current in the wire (in amperes), and r is the distance from the wire (in centimeters).

Explanation / Answer

Here,

H = 2I/(10r)

given that -

I = 8 A, r = 5 cm

put this in the above expression -

H = (2*8) / (10*5) = 0.32 Oersteds.
