22N.2.SL.TZ0.c.i

Explain, by reference to charge carriers in the wire, how the magnetic force on the wire arises.

[2]

Markscheme

charge/carriers are moving in a magnetic field ✓

 

there is a magnetic force on them / quote F = qvB

OR

this creates a magnetic field that interacts with the external magnetic field ✓

 

Accept electrons.

For MP2, the force must be identified as acting on charge / carriers.

Examiners report

Many scored MP1 here but did not get MP2 as they jumped straight to the wire rather than continuing with the explanation of what was going on with the charge carriers.
