Describe an experiment to show that a current carrying conductor produces magnetic field.
Answers
Answer:
The conductor is kept in N-S direction and its ends are connected to a battery, rheostat and a tapping key. ... As the key is pressed and a current passes in the conductor, the needle deflects. This shows that a magnetic field Exists around a current carrying conductor.
Answer:
A battery cell
10cm long insulated wire
Electrical tape
A strong neodymium magnet
Pen and paper to record your observation
Magnetic Effect
Step 1: Grab the insulated wire, strip off the insulation around 1 cm on each side.
Step 2: Connect one end of the wire to the positive terminal of the battery, use the electrical tape if necessary.
Step 3: Place a strong neodymium magnet under the wire, do not connect the wire and note down your observations.
Step 4: Now connect the free end of the wire to the negative terminal and see what happens, note down your observations.
Step 5: Now keep the wire as it is and interchange the terminals of the battery, notice what happens. Note down your observations.
Inference: we can see that the wire bends when there is current flowing through it, and when the polarities are inverted the wire bends in the opposite direction.
A current-carrying wire in a magnetic field experiences a force.
The magnitude of the force depends on the magnitude of the magnetic field and the current flowing through the conductor.
The direction of the force also depends on the direction of the current flowing through the conductor.
This is because current flowing through a conductor induces a magnetic field around the conductor, this can be easily understood by the right-hand rule, which states that if you make a thumbs up sign with your right-hand then the thumb pointing in the direction of the current and rest of your fingers indicate the direction of the magnetic field.
Magnetic Effect
When you apply current to the conductor it will produce a magnetic effect or field around it, so basically the wire acts like a magnet, and it will interact with the permanent magnet you have placed next to it, this effect can be reversed by changing the direction of the current, which according to the rule changes the direction of magnetic field produced by it.
We know that in magnets like poles repel and unlike poles attract each other, so depending on the direction of the magnetic field induced, the conductor will either get attracted or get repelled by the permanent magnet.
