We dont know yet what like the magnetic field of the dwarf planet 1 Ceres is. No space probe had yet visited Ceres. But that will change in 2015 when the NASA:s Dawn probe will settle to orbit around Ceres. Dawn will reveal do Ceres have a magnetic field or not. Before the probe reaches Ceres it will orbit another minor planet the asteroid 4 Vesta for nine months from August 2011 until May 2012. If Vesta has a magnetic field Dawn will discover it too. Vesta is the second most massive main-belt asteroid. Only Ceres is more massive. Vesta may also be reclassified as a dwarf planet like Ceres rather than staying just as a small solar system body like smaller minor planets.
Electric charge produces an electric field by just sitting there. It doesn't have to move. If it moves, it produces a magnetic field. It doesn't matter how the motion would be described.
No, only iron is manetic.
Magnetic field induction at a point is defined as the FORCE experienced by a unit north pole placed at that point. Since force is a vector quantity, manetic field induction also becomes a vector quantitiy.
Any current will produce a magnetic field. If you let a current pass through the wire, you got your magnetic field.Note: If you connect the wire directly to the battery, without any resistance, you'll most likely destroy the battery, due to a short circuit.
magnetic field is a imaginary area around a manetic material where other magnetic subestences experience some force but flux is the imaginary lines of force that arise from magnet which indicate direction of force around it.
Tebi-Manetic and S.S.D. Solution are the chemicals that are used to turn money into normal.
A US dime is not magnetic. It is composed of 90% silver and 10% copper and neither of those metals are magnetic.
EMF can be produced either by change of flux through a particular area kept in a magnetic field in a particular interval of time ( called self induced emf) or by the motion of any conducting rod in manetic fied....
It points in a northerly direction towards the North Magnetic Pole (which is close to, but not the same as the North Pole)
Flux density is the number of magnetic lines crossing per unit area in perpeendicular direction. It is named as manetic field induction, B. Unit is tesla or weber/m2 Unit for magnetic flux is weber in SI system. Fl
This is not a change at all. However it is physical when you use a magnet to physically seperate (by manetic force) .
the responibilty of physcial layer is to move data(bits) from one node to another in the form of electro manetic signal.
