Magnetic fields Watch
I think s for second
not sure for last...
So so sorry if its A level, I haven't got there yet
Wish the best of luck!
Wouldnt the magnetic field be strongest at Q? Since the wire is coming out of the paper and if you use the right hand rule, you’d find that the magnetic field lines are going in the same direction. This means that they would ATTRACT. The magnetic field lines would overlap and create a maximum.
The magnetic field lines where they overlap add up. So surely if the magnetic field is going in the same direction, it should maximise. Btw If you’re doing A Level Physics, it’s kind of like the concept of superposition of waves.
So surely if both currents are coming out of the page, at that point in the middle, one would be travelling counter clockwise and the other would be clockwise. Therefore they would cancel?
