What is the simulation theory?

Inessa05 [86]

The simulation hypothesis<span> contends that reality is in fact a simulation (most likely a </span>computer simulation<span>), of which we, the simulants, are totally unaware. Some versions rely on the development of simulated reality, a fictional technology.</span>

An electromagnet is strong enough to lift 200 kg of mass. If you double the number of turns of wire around the core and triple t

VLD [36.1K]

Answer:1200 kg

Explanation:

Given

Electromagnet can lift a mass of $200\ kg$

Magnetic force necessary to hold mass is proportional to Magnetic field

and magnetic field (B) is proportional to NIA

where N=no of turns

I=current in the magnet

A=area of cross-section

When we double the no of turns and triple the current then

N becomes 2 N

I becomes 3 I

therefore magnetic field becomes 6 times

Thus magnetic force becomes 6 times and we can say that electromagnet can hold the 6 times of given weight

i.e. $6\times 200=1200\ kg$
