Which of the loops would feel a magnetic force directed to the right?

In summary, the direction of the magnetic force on a loop in a magnetic field is determined by the direction of the current and the magnetic field. It can be changed by altering either the current or the magnetic field. The size of the loop does not affect the direction of the force. The right-hand rule can be used to determine the direction of the force and it can be controlled by changing the parameters of the circuit or using devices such as electromagnets.

Problem:

The figure shows a region of uniform magnetic field out of the page. Outside the region, the magnetic field is zero. Some rectangular wire loops move as indicated. Which of the loops would feel a magnetic force directed to the right?

Attempted Solution:

By right hand rule none of these had a magnetic force to the right.

NOPE. Not right. Not sure why its not right either.

Possible Solution Choices:

a) 1
b) 2
c) 3
d) 4
e) 1 and 2
f) 2 and 4
g) 3 and 4
h) none of them

The induced force opposes the change in flux through the loop.
 

Related to Which of the loops would feel a magnetic force directed to the right?

1. What is the direction of the magnetic force on a loop in a magnetic field?

The direction of the magnetic force on a loop in a magnetic field is dependent on the direction of the current flowing through the loop and the direction of the magnetic field. If the current and magnetic field are perpendicular to each other, the force will be perpendicular to both and will follow the right-hand rule. This means that the force will be directed to the right side of the loop.

2. Can the direction of the magnetic force on a loop be changed?

Yes, the direction of the magnetic force on a loop can be changed by altering the direction of either the current or the magnetic field. For example, if the current is flowing in the opposite direction or the magnetic field is flipped, the force will be directed to the left side of the loop instead of the right.

3. How does the size of the loop affect the direction of the magnetic force?

The size of the loop does not affect the direction of the magnetic force. As long as the current and magnetic field are perpendicular, the force will always be directed to the right side of the loop.

4. What is the significance of the right-hand rule in determining the direction of the magnetic force?

The right-hand rule is a simple way to determine the direction of the magnetic force on a current-carrying wire or loop. By pointing your right thumb in the direction of the current and your fingers in the direction of the magnetic field, the direction in which your palm faces will indicate the direction of the force.

5. Can the direction of the magnetic force on a loop be controlled?

Yes, the direction of the magnetic force on a loop can be controlled by changing the direction of either the current or the magnetic field. This can be achieved by adjusting the parameters of the circuit or by using devices such as electromagnets to manipulate the magnetic field.
