Why is there a magnetic field even when there is no current?

Physics

zepelin [54]3 years ago

I understand that electric field can exist without any magnetic field, although it is also generated by varying magnetic field, but as much I know, magnetic fields don't exist independently, they are generated by varying electric field or moving charge. Even in any magnetic substance, magnetic field is generated due to electrons orbiting the nucleus, and electrons have their own electric field, so electric field is present there as well.

How much heat is needed to boil 5.30 kg of water at its boiling point?
vivado [14]

Answer:

Required heat Q = 11,978 KJ

Explanation:

Given:

Mass = 5.3 kg

Latent heat of vaporization of water = 2,260 KJ / KG

Find:

Required heat Q

Computation:

Required heat Q = Mass x Latent heat of vaporization of water

Required heat Q = 5.3 x 2260

Required heat Q = 11,978 KJ

Required heat Q = 12,000 KJ (Approx.)

If a rigid body rotates about point O, the sum of the moments of the external forces acting on the body about point O equals whi
Drupady [299]

Answer:

The answer to the question is A.

Explanation:

The definition of moment is Force multiplied the distance to the point of interest.

 So the external moment at point O is equal to ⇒ EMо= F×d

 Knowing the definition of moment of inercia (I) and a newtonian Force ( m.a)

We can say that te moment of the externals force at point O is EMо= IGa

Because the rotation of a body in a inmovil point is implicated by the moment of inercia an the action of the gravity in that moment.

WILL GIVE BRAINLIEST
Diano4ka-milaya [45]

Answer:

nice to help you

Explanation:

If for any reason the Sun shrank smaller than the Earth, this shrunken Sun wouldn't have the mass to create fusion and would burn out completely. Our solar system would lose its only star. ... Earth's mass would be at least 333,000 times bigger than it is now. Imagine the gravity that planet would have.
