Please answer and explain why. Thank you.
A magnetic field exerts a force on a current carrying conductor. On any differential length of the conductor dl (where the bold denotes a vector), the force is given by dF = I dl times B where the X denotes the cross-product. The figure shows a diagram of a battery on top of a magnet, with current I flowing in the copper colored wire. (The surface off the magnet is conductive and closes the circuit back to the battery). The cylindrical magnet has a dipole magnetic field, denoted by the magnetic field lines going from the magnet's north pole to its south pole (outside of the magnet). The arrows show the direction of the magnetic field at each location. The component of the magnetic field which is perpendicular to the direction of current flow creates a force on the wire in a direction given by the right hand rule. In your notebook, draw four diagrams (two orientations of the battery, either + or - on top, and two orientations of the magnet, either Nor S on top) showing the direction of the current at a location adjacent to the top of the magnet, the direction of the magnetic field there, and the resulting direction of the force. (Use a circle with a x in it denoting "into" the paper, and a circle with a dot in it denoting "out of" the paper.) Use the right hand rule to get the force direction. There are various hazards associated with the magnets. The most likely hazard here is that your finger will get pinched between two magnets, so once you have a pair together, please leave it that way. Do not let different pairs of magnets get close enough together to combine if possible. They could shatter, and they are hard to separate. Most importantly, when you take your motor home, do not let any young children play with the magnets. If strong magnets are swallowed separately, they can attract each other in the intestines, gradually making a hole in the intestines and potentially causing death.Explanation / Answer
here field B at wire is towards right. dl vector is downward.
dl x B will be in direction out of the page.
So force experienced will be towards out ofbthe page
use right hand rule, thumb points toward current, index finger towards field and middle finger towards force
