Why Does Fleming's Right Hand Rule Give an Upward Force on the Wire?

In summary, the conversation discusses the use of Fleming's hand rules to determine the direction of force on a current-carrying wire placed between two magnets. While the right hand rule may suggest an upward force, the left hand rule should be used for accurate results. Helpful resources are provided for further clarification.

Fleming's hand rules

The Attempt at a Solution


I used the Flemings right hand rule but that gives me that the force on wire is upwards. But the answer is otherwise. Thanks for your help!

FAQ: Why Does Fleming's Right Hand Rule Give an Upward Force on the Wire?

1. What is the direction of the magnetic force?

The direction of the magnetic force is perpendicular to both the direction of the magnetic field and the direction of the moving charged particle.

2. How do you determine the direction of the magnetic force?

The direction of the magnetic force can be determined using the right hand rule. Point your thumb in the direction of the moving charged particle, your fingers in the direction of the magnetic field, and the palm of your hand will face the direction of the magnetic force.

3. Does the direction of the magnetic force change?

Yes, the direction of the magnetic force can change depending on the direction of the magnetic field and the direction of the moving charged particle.

4. What is the significance of the direction of the magnetic force?

The direction of the magnetic force is important because it determines the direction of motion of a charged particle in a magnetic field and is crucial in understanding the behavior of electromagnets and electric motors.

5. Can the direction of the magnetic force be manipulated?

Yes, the direction of the magnetic force can be manipulated by changing the direction of the magnetic field or by changing the direction of the moving charged particle. This is how electromagnets and electric motors are able to function.
