Right-hand Grip rule Demonstration part A

we know that wires carrying currents produce magnetic fields, but now we need to determine the direction of the field

AIM: To determine the shape and direction of a magnetic field that forms around a current-carrying wire.

Method:1. your teacher will set up the wire carrying a current so that it travels vertically, and through a platform, as shown in the diagram below

             2. they will then sprinkle iron filings on the platform near the wire.

             3. after turning the power supply on your teacher will tap the platform to allow the iron filings to move.

Conclusion: outline what this demonstration taught you about the shape of magnetic fields that form around wires carrying a current.

we put two wires and connected it to the power supply and we put iron filings on some board and when we turned it on the iron filings followed the magnetic flow. the nail was carrying the magnetic field around it then the iron fillings showed the magnetic field.

Part B

Method:1. Your teacher will replace the iron fillings with a number of small compasses that form a circle around the wire.

2. Note the direction that the compasses are pointing.

3. Ensuring the current is flowing upwards through the platform, your teacher will turn on the power supply.

4. Now note the direction that the compasses are pointing.

5. With the power supply changed so the current flows downwards through the platform, note the direction the compasses are pointing 

Conclusion: Outline what this demonstration taught you about the direction of magnetic fields that form around current-carrying wires.

When the magnetic field is being pulled around the nail and then you get the compass the compass will be pulled to that magnetic field and the compass will follow the magnetic field
