How does gravity affect magnetic fields?

Magnetic fields are ‘polar’ fields with a North and South polarity. Gravitational fields have no polarity at all. At large distances, gravitational fields diminish as the inverse square of distance from their source. Magnetic fields at large distances from their source, decrease as the inverse cube of the distance.

What is formed when the magnetic fields of atoms are aligned in the same direction?

What does gravity and magnetic force have in common?

Gravity is a force that acts between any two objects with mass. No matter what they are made of, both objects get pulled towards each other just because they have mass. Magnetism can either pull the two objects together or push them apart, depending on which way the magnets point.

How are gravitational electric and magnetic forces and fields similar?

They both have a point source, and with this point source they both have a field intensity that is proportional based on the inverse square law. Both exert force from a distance with no contact.

Does a magnetic field create gravity?

Because an electromagnetic field contains energy, momentum, and so on, it will produce a gravitational field of its own.

Is gravity due to magnetic field?

Hidden extra dimensions are causing measurements of the strength of gravity at different locations on Earth to be affected by the planet’s magnetic field, French researchers say. But lab measurements of Newton’s gravitational constant G suggest that both are real.

Which type of loops are formed by the magnetic field lines?

Magnetic field lines are continuous, forming closed loops without beginning or end. They go from the north pole to the south pole.

What are groups of atoms with aligned magnetic poles called?

Groups of atoms with aligned magnetic poles are called magnetic domains. The magnetic fields of these aligned domains add together and create a strong magnetic field inside the material.

What do all magnetic objects have in common?

All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.

How does a magnetic field affect the motion of a particle?

The velocity component perpendicular to the magnetic field creates circular motion, whereas the component of the velocity parallel to the field moves the particle along a straight line. The pitch is the horizontal distance between two consecutive circles. The resulting motion is helical.

What is a magnetic field?

Magnetic field: 1) A moving charge or current creates a magnetic field in the surrounding space (in addition to E). 2) The magnetic field exerts a force F m on any other moving charge or current present in that field. – The magnetic field is a vector field vector quantity associated with each point in space.

How do magnets align themselves to make them permanent?

In response to an external magnetic field, the domains may grow to millimeter size, aligning themselves, as shown in Figure 7 (b). This induced magnetization can be made permanent if the material is heated and then cooled, or simply tapped in the presence of other magnets.

What are the similarities between Proton and electron magnetic forces?

Compare their accelerations. The magnitude of the proton and electron magnetic forces are the same since they have the same amount of charge. The direction of these forces however are opposite of each other. The accelerations are opposite in direction and the electron has a larger acceleration than the proton due to its smaller mass.
