Question

at what distance from a long straight wire carrying of 12 ampere will be the Magnetic field B equal to 7 ×10^- 5 wbm^-2​

Answer 1

Answer:

distance from a long straight wire carrying of 12 ampere will be the Magnetic distance from a long straight wire carrying of 12 ampere will be the Magnetic field B equal to 7 ×10^- 5 wbm^-2 B equal to 7 ×10^- 5 wbm^-2

the strength of the magnetic field change when the point where the strength of the magnetic field change when the point where magnetic field is the be determinde is moved away from the straight wire carrying constant current field is the be determinde is moved away from the straight wire carrying constant current
