Oh I think I understand the problem now. The magnet would enter the solenoid, then when the south poles meet, it will be repelled back out, then back in, then back out etc.? So it will oscillate near the opening of the solenoid?

I suppose it would stop when the 2 south poles come in contact? Would the bar magnet then be repelled back out?

Thanks for the welcome! :smile: So the bar would be simply be attracted? How close would it move to the solenoid before stopping? Would anything else occur?

1. The problem statement, all given/known data A bar magnet is positioned at the mouth of a solenoid. The current indicated in the solenoid is then turned on. (Assume the solenoid is a lot bigger than the bar magnet.) Gravity and friction can be ignored. Describe what would happen, and...

Sorry just realized I posted this in the wrong subforum. Can a moderator please move it to the 'Introductory Physics' subforum? Thanks and sorry.

Use Eg = mgh to find how much work the man does. Then use mikelepore's indicated site to calculate power.

Alright, I got the answer. :cool: Thanks. Another similar inquiry: A N S bar magnet is placed near a S N solenoid. Would the magnetic field be the same as if the solenoid was simply another bar magnet?

I suggest you ask your teacher for extra help. If you're having trouble with all of these questions, it means that you're having difficulty understanding the concepts behind what you're learning.

1. The problem statement Is the magnetic field around the following two bar magnets: |N S| + |S N| the same as the magnetic field around: |S N| + |N S|? 2. The attempt at a solution Yes, but the arrows on the lines move in opposite directions?
