Answer to Question #157967 in Physics for Duc

Question

A circular wire frame consists of 24 turns of wire, each ring of wire

has a current of 0.5A running through. According to calculations, the magnetic induction in

wire frame center is 6,3.10-5T. But when measuring, the magnetic induction

in the heart only 4.18.10-5T.

Answer 1

If the question is why the experimental value is less than the estimated, then there may be several reasons:

• assumptions that are accepted when deriving the formula;
• accuracy of the experiment;
• experimental technique, etc.
