Talk:A-level Physics/Electrons, Waves and Photons/Magnetic effects of current

Specification
From the OCR GCE Physics A specification. Tick with &#10004; when you feel each part of the specification has been covered. Try not to add much more than what is in this list as it would not appear in the exam anyway. Use links to wikipedia for more depth in a topic.


 * 1) Sketch magnetic field patterns caused by current in a long straight wire, a flat circular coil and a long solenoid.
 * 2) Appreciate that a force may act on a current-carrying conductor placed in a magnetic field.
 * 3) Recall and use F=BIl, with directions as interpreted by Fleming’s left-hand rule.
 * 4) Define magnetic flux density and the tesla.
 * 5) Use Fleming’s left-hand rule to predict the direction of forces acting on two long, straight parallel current-carrying conductors.
 * 6) Understand that the forces between current-carrying conductors provide the basis of the definition of ampere – no definition required.
