With _____ in current in a wire near to magnetic needle, _____the vibration in the needle. Fill in the blank.

  1. increase, decreases

  2. increase, increases

  3. decrease, increases

  4. Non of above

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

More is the current in the wire near to the magnetic field, more is the strength of magnetic field generated around the wire and thus more is the vibration in the needle.

What did Orested do in the experiment ?

  1. Placed a compass near an electromagnet and observed its deflection

  2. Placed a compass near a magnet and observed the deflection of compass needle

  3. Placed a compass near a current carrying wire and observed the deflection of compass needle

  4. Placed a compass near an electrolyte and observed the deflection of compass needle

C Correct answer
Explanation

Hans Christian Oersted. Hans Christian Oersted began a new scientific epoch when he discovered that electricity and magnetism are linked. He showed by experiment that an electric current flowing through a wire could move a nearby magnet.Oersted's experiment that when an electric current is passed through a conducting wire, a magnetic field is produced around it. The presence of magnetic field at a point around a current carrying wire can be detected with the help of a compass needle

The amount of deflection of the magnetic needle in a galvanoscope depends on:

  1. The amount of current passing through the insulated copper wire that is wound over it

  2. Magnetic strength of the magnetic needle

  3. Number of turns of the coil

  4. All the above

D Correct answer
Explanation

The deflection in galvanometer is the defined by 

$\tau=NBIA$
The N is number of turns of coils.
B is magnetic strenght of magnetic needles 
I is The amount of current passing through the insulated copper wire that is wound over it
A is area of coil contact with magnetic field.

What did Oersted observe while performing the experiment ?

  1. The compass needle placed near an electromagnet deflected

  2. The compass needle kept near an electrolyte deflected

  3. The compass needle kept near a wire carrying electric current deflected when the current was switched ON and OFF.

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Oersted observed while performing the experiment when he passed a current through a wire which caused a nearby magnetic compass needle to move.When current switched off then needle comes to their original position

What did Orested discover from his experiment ?

  1. Heating effect of electric current

  2. Magnetic effect of electric current

  3. Chemical effect of electric current

  4. Physical effect of electric current
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In the experiment of Oersted's he passed electric current through a wire,which caused a nearby magnetic field so that compass needle move.That shows that magnetic effect of eclectic current.
