Maximum magnetic force on a wire in a magnetic field

[pratyushag]

Homework Statement

A wire of length L is placed in a magnetic field B,If the current in the wire is I,then maximum magnetic force on the wire is?

Homework Equations

The Attempt at a Solution

Honestly,I have no idea how to do this..(Im in class 9)

You should have an equation that gives the magnetic force on a wire of some length with some current running through it.

 

[pratyushag]

what is the equation?

 

[SHISHKABOB]

it should look something like F = BIL

do you recognize it?

Im sorry I am coming across this the first time... could u explain it please

You say you are in class 9, i doubt it that i was taught this when i was in class 9. Are you taking any tuition or something to learn this extra stuff?

And about the question, you should first refer some book to learn about the force on a current carrying wire in a magnetic field.

 

[SHISHKABOB]

If this is a homework problem for school, then you certainly must have been shown this equation before. If it's not a homework problem, then I suggest doing what Pranav-Arora said and going and looking it up.

Yes i am in class 9, and yes i have been taking special tuition...

I have completed the class 9 syllabus of science and have completed class 10(physics&maths).
I know all about Oersted,Flemings right hand,left hand,electromagnetic induction
Moreover i have started training for the Indian National Physics Olympiad (INPhO) and Regional Mathematical Olympiad.

I encountered this problem in one of the sample papers of an IIT-JEE instituiton
hence i was asking about it,and i have never seen or taught this equation ever,i tried looking up the net but found gibberish...
So could you please explain or provide a suitable link?

Instead of completing everything in rush and directly trying to reach the JEE paper, better first complete your textbooks, i remember, there's a lot of stuff in them. Buy a good book rather than dwelling on net for the information.

Force on a (current carrying conductor) this is the wire in your case, lying at right angle to a magnetic field can be given as:

F=BIl
B=flux density, magnetic field in your case
I= current
l=length of the wire
