Please help! A straight wire is placed in the magnetic field of a U-shaped magnet as shown in fig. 1 (attached) The length of the wire in the field is 35 mm. When a current of 1.8 Amp is in the wire, a force of 0.024 N acts on the wire due to the field. Calculate the magnetic flux density of the field. Thank you for helping (if you can!)

answer: a ball

explanation: because it will bounce

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.
