How do I measure the force on a current carrying wire in a uniform magnetic field?
F = BIL

Where F is force, B is the Magnetic flux in Tesla, I is the current in amps and L is the length of the wire in the magnetic field in metres.

Multiple BIL and get D.

Thank for your REPLY!
But actually I was trying to do practically by using F=BIL.
But I have no clues with which experiment and apparatus to try with.
If you have any ideas that comes up or websites that would help me to guide with systematic procedure and specific experiments to find the force on a current carrying wire in a uniform magnetic field. Thanks a bunch again:colondollar:!!

Lucky you! I have done this experiment before.

So take a wire and use a metre rule to measure the length of the wire. use an amp metre to measure the the amount of alternating current in a wire (using direct can heat the wire up). Use a hall probe and callibrate it to measure the magnetic field density, you can use any object that gives out a magnetic field.

And voila. Multiply the three
Just clamp a wire in magnet over a weighing scale. It will exert opposite force on scale. Use this for a couple different values of current, plot a graph...

If you're doing aqa a level all the experiments are in this booklet:
