Homework Help: Electromagnetism Explaining Question

  1. Jun 4, 2009 #1
    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 why.

    For a visual representation:

    2. The attempt at a solution

    To try and solve it I drew the above diagram. Since the north pole of the bar magnet is facing the south pole of the solenoid I suppose they would attract?

    But I feel like there's something else that would happen (ex. something more drastic since the solenoid is much more massive).

    Any help/explanations will be greatly appreciated! :smile:

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