Pls help 16. Outline how Oersted accidentally discovered that an electric current creates a magnetic field.

17. Identify two factors that affect the magnetic field surrounding a wire that is carrying electric current.

See explanation

Explanation:

16.

Ironically, Oersted made his discovery during a lecture where he was trying to show to students that electricity and magnetism are in fact not related. Using a compass and a wire with current, he showed that the needle of the compass pointed toward the earth's north pole. However, a student accidentally found out that moving the wire made the compass needle turn, which prompted Oersted to rethink his ideas.

17.

A magnetic field is largely affected by temperature, since a higher temperature causes the molecules in the wire to jiggle faster, and make the flow of electrons more difficult. The field is also affected by the material that the wire is made out of, because this once again impacts the conductivity of it and how much electricity can flow through it.

Hope this helps!
