Hi, I am a year 12 student and I have some some questions about magnetic fields.
Do all magnetic fields (in particular ones produced by electromagnets) have distinct poles?
How does a force act an object carrying current under presence of a magnetic field.
##F=BIΔlsinθ##
(force on a current carrying conductor in a magnetic field)
I was talking to a physics teacher today, and I asked in the case of a wire carrying current, does it have poles like a solenoid? My teacher said the solenoid acts like a bar magnet and the magnetic field lines touch the conductor, giving it north and south poles on the ends. In the case of a wire, the magnetic field lines are circular around it, and as the magnetic field lines never touch the wire, no poles are produced.
I was then thinking, if the wire has no poles, why then is a force experienced on the wire when placed under presence of a magnetic field? Aren't all magnetic field forces caused by north and south poles interacting? In a way similar to how electric fields are affected by positive and negative charges?
I would appreciate a push in the right direction, I feel like our physics dosen't go very much in depth. Thank you in advance.
