If I throw a conducting coil in air which has N loops wound together and the coils starts rotating or spinning in the mid air, will there be any induced EMF/current in the conducting loops due to Earth's Magnetic field?

A simpler question will be', Does Faraday's law work in Earth's magnetic field?

Faraday's Laws hold in all magnetic fields.

Theoretically, there'll be a current. But that will be probably of a very very low magnitude, as the speed required (or the angular velocity required) to produce a current with earth's magnetic field should be quite high.

Taken from a clearly theoretical view, the experiment would work. From practical viewpoint, one has to do and see.

Yes. Its an experiment I had to do as an undergrad. Although not throwing in the air but rotating on the desk.
