Magnetic forces are those that act on magnetic objects or charged particles moving through a magnetic field. The practical uses of...
Metals can be magnetic and non-magnetic. The magnetic ones will produce a field around them, usually described as “ferromagnetic.” These metals are not magnetic by themselves in their natural state. Still, they can be attracted to objects that produce magnetic fields. Once magnetized, these me...
structure. All objects in the universe are made of atoms, and each atom has a nucleus at its center. Tiny particles called electrons orbit the nucleus, creating magnetic fields around them. Magnetism occurs when the electrons spin in the same direction. As all the magnetic forces from the ele...
Dzig-zag linesSubmit Magnetic lines of force are Adirected from the north pole to south pole in the magnetic field Bdirected from the south pole to north pole inside a magnet. Cclosed loops DAll the aboveSubmit Give four properties of electric lines of force. Or. Give important propert...
depend on magnetic fields and forces as much as they would need to for magnets to damage them. Other technology such as cables can be affected if they aren't appropriately protected from external magnetic fields. Most cables are designed to prevent external magnetic fields from harming their use...
The weak and strong forces are effective only over a very short range and dominate only at the level of subatomic particles. (ii) Weak Nuclear Force - Next weakest, but short range. Doubtnut is No.1 Study App and Learning App with Instant Video Solutions for NCERT Class 6, Class 7, Cla...
What are magnetic field lines?Magnetic Field Line:Force is defined as any push or pull. Earlier, physicists knew only of contact forces which can act only when contact is made but later Issac Newton could describe non-contact forces such as gravitational force. Non-contact forces act at a ...
What is the force of magnetic force? What are the four forces? What are the different types of force system? What are some examples of force and motion? Explain and exemplify what is the net force. What are contact forces? Give examples. What work was done by the electric force? How ...
2. Which of the following are action at a distance forces? a) air resistance b) normal forces c) magnetic forces d) frictional forces 3. What is the force that opposes the relative motion or tendency to such motion of two bodies in contact a) magnetism b) the normal force c) gravity...
Then there are tidal forces. A moon might get too close to the planet and get broken apart by Saturn's tidal forces. Female student: Excuse me. You mean, tidal forces, like high tide and low tide on the oceans? Male professor: Well, by "tidal force," I'm referring to the gravitati...
