If the number of turns of a solenoid circular coil is doubled, but the current in the coil and radius of the coil remain the same, then what will be the magnetic flux density produced by the coil?
- A
Magnetic flux density will be halved
- B
Magnetic flux density increases by different amount at different points
- C
Magnetic flux density remains unchanged
- D
Magnetic flux density will be doubled
When the number of turns N is doubled but the solenoid length L also doubles, the magnetic flux density B=μ0(NI/L) remains the same. Therefore, there is no change in B.
