Questions
Magnitude of magnetic field (in SI units at the center of a hexagonal shape coil of side 10 cm, 50 turns and carrying current I (Ampere) in units of is :
detailed solution
Correct option is B
Magnetic field due to one side at center is B=μ0i4πrsinα+sinβ=μ0i4π3a2sin30º+sin30º =μ0i2π3aThere are 6 sides and 50 turns B=6×50×μ0i2π30.1=5003μ0iπTalk to our academic expert!
