Can somebody tell me the experiments for the following :
1)Force on a current carrying wire
2)On a beam of charged particle in a magnetic field including the effect of reversing i) the current and ii) the direction of the field?

Thanking in advance

Can somebody please answer this for me??????

HELLOOOO??!!!!

1) You take a U shaped magnet. Pass a wire carrying current between them. A force is generated on the wire due to change in magnetic flux as the the magnetic field of wire cuts the magnet field of U shaped magnet. Direction of force can be found using a Left Hand Rule.
2) If the magnetic field is into the page, negative charges move downwards while positive move upwards while if it's out of the page, negative move up and positive move downwards.

1) I guess that's about the Motor effect
2) Don't know

Q.4 e
What would be path of line 3???

Just like line 1. Refract towards normal by drawing the normal at surface, and then away from normal when it leaves.

What is the use of a fudicial marker?

 

[princess Anu]

the compass needle is itself a magnet? its arrow head points away from north or towards north??

They are refernce markings inorder to observe a fixed distance and stop/start stopwatches.

Are you telling about fudicial marker?

Ek saal guzar gya, apka avatar nahi change hua.

Yup

 

[funky brat]

Yup

How exactly does it help in starting/stopping a stopwatch? :/

 

[Fate0]

it's a marking. when you see the ball/bob crossing this mark, you instantly press the stopwatch.

1.61
as we're dealing with moments, the distance of 95cm from the edge is also 5cm.

Hmm Thanks.
