Question

What would happen to the direction of the magnetic force F on the current wire if you were to switch the direction of the current so that it is into the page as shown here? According to Newton's Third Law, for every action there is an equal an opposite reaction. If the current on the wire is such so that the magnetic force on the wire points upward, what must be true? Suppose you have a wire on the current balance of length 1.1 cm and current 4.6 Amps going through a magnet with a field of 0.063 Teslas. What is the magnitude of the Force in Newtons? In the image below, you will see a current balance setup where the current I is coming out of the page in between the two poles of the magnet N and S. What is the direction of the magnetic field B in the region where current / is? In the previous question, what is the direction of the magnetic force F on the wire carrying the current /?

Explanation / Answer

Question 4
The direction of force flips and it points upwards.. U can get this by using Fleming's left hand rule.

Question 5

There is an equal and opposite force on the magnet in downards..But the force is not noticable as thepoles are fixed..

Question 1
Force = Bil = 0.063*4.6*0.011 = 3.1878 mN

Question 2
The direction of magnetic field is from right to left.

Question 3
The direction of force is upwards .. By using flemings left hand rule
