What do magnetic minerals prove the earth has had?
The presence of magnetic minerals in rocks proves that the Earth has had a varying magnetic field over time. This is evidence of the geodynamo process within the Earth's outer core, where convection currents generate the magnetic field.
What can be planted on a septic field?
Grass
MR.Dolan planted 0.75 of a field with corn . the field is 5.5 acres in size .how many acres are planted with corn?
4.125 acres.
Can a transformer work with d.c.?
The primary coil has to induce current in the secondary coil. The only way this can happen is if there is a varying magantic field in the primary which then will induce a varying mag field in the secondary which results in a current in the sec. Only varying current can induce a varying mag field only a varying mag field can induce current So you need a varying current in the primary. D.C. is not a varying current so it cannot induce a mag field in the coil. A.C. (it does not have to be +/- it just has to be varying) can do so.
What are the physical significance of Maxwell's equations?
As per my knowledge,Maxwell's equations describes the relations between changing electric and magnetic fields. That means time varying electric field can be produced by time varying magnetic field and time varying magnetic field can be produced by time varying electric field.
Why was the field to be planted with barley in Animal Farm?
42
What job did most slaves do on the field?
The planted, plowed, and picked the crops.
Corn planted in a field that has been previously planted with legumes and then plowed under is likely to be?
less productive because legumes remove phosphorus from the soil
How can the frequency and voltage of an alternator be changed?
The frequency is changed by varying its speed, and the the voltage is changed by varying its field current.
Why is light in the electromagnetic spectrum Is light a type of electromagnetic radiation But how does that work Light is not magnetic or is it?
Part of the electromagnetic spectrum can be detected by eye, and we call that bit "light". The thing about electromagnetic radiation is that a varying magnetic field causes a (varying) electric field (that's how power stations make electric current) and a varying electric field causes a (varying) magnetic field. So electromagnetic radiation is what you get when a varying electric field creates a varying magnetic field which in turn contributes the varying electric field. The whole thing then appears as bundled varying electric and magnetic field wave system which propagates at the velocity of light, That is why it is called electromagnetic. There are no magnetic poles or electric charges in it, and it can travel through a vacuum.
How does a time-varying electric field lead to the generation of a magnetic field?
A time-varying electric field creates a changing electric flux, which in turn induces a circulating electric current. This current generates a magnetic field according to Ampre's law, leading to the generation of a magnetic field.
How does a time-varying magnetic field lead to the generation of an electric field?
A time-varying magnetic field creates a changing magnetic flux, which induces an electric field according to Faraday's law of electromagnetic induction. This electric field is generated as a result of the changing magnetic field, leading to the production of an electric current.
