By increasing the size of fields there is less wated space therefor more crop is harvested and it is more efficient use of the land Bigger fields are more efficient to care for. You spend less time moving the tractors and harvesters around, and more time working the soil.
No, humans cannot physically feel or hear a magnetic field. Magnetic fields are typically invisible and do not produce any sound that the human ear can detect. However, specialized equipment can detect and measure magnetic fields.
because they are different compared to humans, their female ovaries are larger than human ovaries
Yes if the moon fell on earth it would definetly produce a noticable magnetic field.
yes
Current-carrying wires produce magnetic fields.
Larger magnetic fields.
Yes
I think they can.
Humans produce animals with certain desirable characteristics through selective breeding.
Faraday's Law states that magnetic fields produce a electric fields and vice versa. Also, Ampere's Law states that a change in magnetic fields w.r.t. time creates current.
Yes.
they have to flood their fields for their food - - U
