Magnetic Forces: Calculating Force on Uncharged Bodies

In summary, the conversation discusses the limitations of magnetic force formulas, how to calculate the force on an uncharged body, and the possibility of the paper clip having a small amount of electrical charge despite having a net charge of zero.

The only formulas for forces due to a magnetic field have to do with a charged body.

How can you calculate the force acting on an uncharged body?
And if there is no force, why can you pick up a neutral paper clip with a magnet?

The magnetic force only acts on moving charged particles, but the paperclip has moving charged particles inside it... :wink:

Then how would you determine the force that is acting on the paper clip as a whole.

Can consider that the paper clip DOES have some electrical charge, just that the net charge between the paper clip and the environment is zero.

If the net charge between the paperclip and the environment is zero, then how can it be measured?
By the way, thank you to everyone who has responded so far, its been a big help.
 

Related to Magnetic Forces: Calculating Force on Uncharged Bodies

1. What is a magnetic force?

A magnetic force is a type of force that is exerted between two objects that have magnetic properties. It is a fundamental force of nature, along with gravity and electromagnetic force.

2. How is magnetic force calculated?

Magnetic force can be calculated using the formula F = qvBsinθ, where F is the force, q is the charge of the object, v is the velocity of the object, B is the magnetic field, and θ is the angle between the velocity and magnetic field vectors.

3. Can magnetic force act on uncharged bodies?

Yes, magnetic force can act on uncharged bodies. This is because all matter has some level of magnetic properties, even if they are not visibly magnetic. This is why, for example, a paperclip can be attracted to a magnet even though it is not charged.

4. What affects the strength of a magnetic force?

The strength of a magnetic force is affected by several factors, including the charge and velocity of the objects, the strength and direction of the magnetic field, and the distance between the objects. The direction and orientation of the objects also play a role in determining the strength of the magnetic force.

5. How is magnetic force related to electricity?

Magnetic force and electricity are closely related as they are both part of the electromagnetic force. Moving charges, which create electric currents, can also create magnetic fields. And, conversely, changing magnetic fields can induce electric currents. This relationship is described by Maxwell's equations.
