Does a moving magnetic field generate a current?

Click For Summary

Discussion Overview

The discussion revolves around whether a moving magnetic field can generate an electric current in a wire, particularly focusing on scenarios involving a circular loop of wire and a moving magnet beneath it. The context includes theoretical exploration and practical applications, such as science projects.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant questions if a moving magnetic field can generate a current in a wire, specifically when a magnet is moved underneath a circular wire.
  • Another participant affirms that moving magnets can generate current, referencing applications in audio technology, such as moving magnet and moving coil pickups.
  • A participant expresses interest in conducting a science project that involves creating a current in a wire using a moving magnet.
  • A clarification is made regarding the specific setup being considered, emphasizing a circular loop of wire parallel to the ground with a magnet moving left and right underneath it.
  • A reference to a Wikipedia article on electromagnetic induction is provided, suggesting further reading on the topic.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the specific scenario of generating current with a moving magnetic field beneath a circular wire, and multiple viewpoints are presented without resolution.

Contextual Notes

The discussion does not clarify the assumptions regarding the configuration of the wire and magnet, nor does it resolve the implications of electromagnetic induction in the described setup.

Hey! Not sure if this is a stupid question or not but I was wondering if a moving magnetic field could generate a current in a wire. I know that moving a wire through a magnetic field creates a current but what if you move around a magnet underneath a circular wire. Does that generate a current?

Yes (if you are into Hi-Fi, you will know that there are both moving magnet and moving coil pickups).

Thanks for the answer Svein! I was just wondering because I wanted to do a science project that is reliant on creating a current in a wire with a moving magnet.
 
Actually to clarify my question a little better, I'm not specifically talking about something like a solenoid, where a magnet goes through a coil of wire. Instead would current be generated if there was a circular loop of wire parallel to the ground and a magnet moving left and right underneath this wire.
