Which of the following is equivalent to tesla?
- AAmpere per Newton
- BNewton per Coulomb
- CNewton per ampere-second
- DNewton per ampere meter
Show answer and explanation
Correct answer: (d) Newton per ampere meter
Explanation
The tesla (T) is the SI unit of magnetic flux density (magnetic field strength).
From the magnetic force formula F = BIL, we get B = F/(IL), so 1 T = Newton per ampere metre (N/A·m).
This makes it equivalent to newton per ampere per metre, not the other listed combinations.
