In ørsted’s observation, the current-carrying wire acted like a
a)generator
b)magnet
c)motor
michael faraday based his first invention, the ørsted s observation.
a)electromagnet
b)generator
c)motor

1.    B)    magnet

2.   C)    motor

Explanation:

1)

In Orsted's observation he found that when few small iron piece is placed near the current carrying wires then all the iron pieces will arrange themselves in the circular loop.

This arrangement is always due to the magnetic field produced by the current carrying wire. So as per his observation the current carrying wire will behave like a magnet.

2)

Michael Faraday explained about the Electromagnetic induction laws and he worked on the theories given by Orsted.

So as per his theory when magnetic flux linked with a conductor changes then it will induce electric current.

So his inventions are based upon rotating device

So it is Electric Motor
