Measuring magnetic field of a solenoid

[Majid]

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.
