Q.9) Coil having 1000 turns, radius 1m carries current of 100mA .Calculate magnetic moment of coil... |
|
Answer» Answer: Given : Current (I)=10A, No. of turns (n)=1000 Radius(R)=0.1m,PERMEABILITY(μ 0 )=4π×10 −7 N/A 2
To calculate : Magnetic FIELD at the CENTRE of the coil (B)=? FORMULA to be used : B= 2r μ 0 I×n
Substituting the given values, B= 2×0.1 4π×10 −7 ×1000 ;B=6.28×10 −2 Wb/m 2 |
