Main Question or Discussion Point

My physics teacher today taught my class the formula with magnetic flux density...

Force on a wire in a magnetic field

F = BILsin(theta)

the part i am enquiring about is the B
in which he explained to be

B is the magnetic field strength (measured in Tesla's)

He also said 1T = 1NmA

I enquired about how could this be, because then Force would not be equal to Newtons. I revised it to be 1T = 1N/mA

Note: m is meters, and A is amperes, not milliampers for mA, just saying.

Can anyone tell me if i am right or not

Yes you are correct. If your professor had a little dot in between the N and mA, he would technically be correct too, since a lot of times ratios of units use the little dot, which you could have mistook for multiplication.
