Measuring magnetic field of a solenoid

Click For Summary

Discussion Overview

The discussion revolves around methods to measure the magnetic field inside a solenoid, with participants exploring various experimental approaches and clarifying the context of the inquiry, whether it is for a school assignment or personal interest.

Discussion Character

  • Exploratory, Technical explanation, Homework-related

Main Points Raised

  • One participant suggests constructing a solenoid and using a probe while applying a current of 50 Amps.
  • Another participant notes that there is a "standard" high school experiment for measuring the magnetic field in a solenoid, but mentions it has about a 10% error margin.
  • A later reply questions the orientation of the Hall bar in a Hall probe when inserted into the solenoid, suggesting it may not be aligned correctly for accurate measurements.
  • Another participant recommends using a Hall Probe for measuring magnetic fields, or alternatively, designing an induction experiment to measure induced EMF from a moving solenoid.

Areas of Agreement / Disagreement

Participants express differing views on the methods to measure the magnetic field, with no consensus on a single approach. Some methods are proposed while others question their effectiveness or accuracy.

Contextual Notes

Participants have not fully defined the parameters of the "standard" high school experiment, and there are unresolved questions regarding the accuracy and orientation of measurement devices used in the proposed methods.

Who May Find This Useful

Students working on physics experiments related to electromagnetism, educators seeking to understand common measurement techniques, and hobbyists interested in practical applications of magnetic field measurements.

hi

I need an experiment to measure magnetic filed in a solenoid.
could anyone help me?

Make a solenoid, crank it up to 50 Amps, and stick a probe in!
 
Is this a school assignment, or just personal interest? Is it something you want to actually carry out, or do you just want to know how it's done? THere are a couple of ways to do it; there is a "standard" high school experiment that determines the magnetic field inside a solenoid, but it has about 10% error.

Typically the longitudinal direction of of the Hall bar in a Hall probe is parallel to the length of the probe. So, if you stick a probe into a solenoid, wouldn't the Hall bar be pointing the wrong way (along the axis of the solenoid) ?
 
Dear chi meson
This is a school assignment. can you explain that "standard" high school experiment that determines the magnetic field inside a solenoid?
Thank You.
 
Majid, you typically use a Hall Probe to measure B-fields. In the absence of a Hall Probe you could design an induction type experiment and measure the induced EMF due to a solenoid moving at some known rate.
