So in my physics worksheet paper there was a maths related question

The teacher was in a rush and didn't really explain much and asked to derive this formula

And I was so clueless (yea the teacher isn't good)

Here is the question

The magnetic force F that acts on a current carrying conductor in a magnetic field is

F=BIl

Where i is the current , l is the length of the conductor

The unit for magnetic flux density B is the Tesla

Express the Tesla in base units
