+267 Hey, I apologize in advanced as this is more of a physics question.
Suppose you have a conductor going through a horseshoe magnet and a current is applied through it. Let l be the length of the conductor that is affected by the magnetic field(length of the horseshoe magnet in this case) Let B be the flux density of the magnetic field and I the current.
We can then calculate the force F by taking the cross product of I and B and multiplying by the scalar l
\(\vec F = l(\vec I \times \vec B)\)
Let's say this magnet is placed on a scale. Let m be the mass that is displayed by the scale. When I is zero we would only get the mass of the magnet. I understand this might be a somewhat silly question but what is the mass of the force acting downwards as described above. I obviously understand F = m*a but would acceleration be just the gravity vector? I am unsure because the force was being caused by the magnetic field and might therefore have a different acceleration because of it. My initial guess is that a is equal to earth's gravity approximately -9.82 N. Could someone confirm or correct me? Really appreciated, thanks in advance.
