Question

I need the questions to this lab answered please!!! Magnets and Electromagnets PHET Lab.

Move the compass around the bar magnet. 1) Which pole of the magnet does the red compass needle point towards?

Click "Flip Polarity" in the right menu. 2) Now which pole of the magnet does the red needle point towards? Does it still point towards the same pole?

3) This means that the red part of the needle is a "????" pole.

Click reset all in the right menu. Check the box "Show Field Meter" in the right menu. A blue box should appear. This measures the magnetic field around the magnet (which is hown as 'B'). the magnetic field is meaured in GAUSS (G). Move the field meter around the magnet. 4) Does the firld increase or decrease as you move the meter closer to the magnet?

Move your meter do that it is about one inch (on your own computrt screen) away from the North end of your magnet. 5) what is the magnitude of field strength (B) in Gauss?

Now move the meter the same distance away from the South end of your magnet. 6) Is the amount of magnetic field the same for both North and South ends of a magnet?

At the top left of the simulation window, click the Electromagnet tgab. you should see a battery connected to a wire with loops that has current running through it. Move your compass around the electromagnet. 7) Is the left side of the electromagnet the North end or the South end? How do you know?

Click "show field meter" in the right menu. Move the meter around the electromagnet. 8) Does the firld strength increase or decrease as you move the meter closer to the electromagnet?

Explanation / Answer

1.The red compass needle point towards the north of the magnet because the compass needle red point is magnetic ally south .. sa south attracts north the red pointer points towards north.

2.After flipping the polarity the south pole comes into picture and the other side of the compass needle(painted white or black) point outs the south pole.

3.this means that the red part of the needle is a south pole.

4.As you move the meter cloase to the magnet the field increases. The meter senses high magnetic field as it approaches nearer to the bar magnet, because the magnetic field will flow radially outwards in a pattern creating magnetic dipoles.

5.The value of B must be observed in your meter while you are experimenting in your lab, kindly check the meter for the B value(gauss meter).
