Force of attraction is a force that pulls the body near due to its attraction. There are numerous attractive forces prevailing in nature. Some of them are magnetic force, electric force, electrostatic force and gravitational force. Gravitational force is very well-identified instance force of attraction as...
magnetic repulsion becomes magne tic attraction. That is why antielectron rushes after the escaping neutron. Neutron cannot escape antielectron because the magnetic forces acting on neutron and antielectrons are equal while the mass of neutron is three orders higher than the one of antiel ectron.
2. State where you will see repulsion or attraction between the bar magnets. 3. Draw a magnetic field for each of the following examples. A) B) 4. The circles below represent compasses. In each situation, draw the needles of the compasses, using an arrow to show the direction they point. a)
Magnetic force on a wire 21/11/2017 Clearly, the size of the force on this wire depends on these things: 1) The strength of the magnetic field 2) The current in the wire 3) The length of the wire (in the field) These things are related by the simple formula… F = BIL B is called “magnetic flux density” and is measured in Teslas.
Attraction, Repulsion, And Static Electricity PPT. Presentation Summary : attraction. Some elements are attracted to others and mesh well with others while some do not.
Even though there are no such things as isolated magnetic charges, we can still define the attraction and repulsion of magnets as based on a field. In this section, we define the magnetic field, determine its direction based on the right-hand rule, and discuss how to draw magnetic field lines.
A new formula for the interaction force between two magnetic dipoles in a uniform magnetic field is derived taking their mutual magnetic interaction into consideration and used to simulate their relative motion. Results show that when the angle β between the direction of external magnetic field and the centerline of two magnetic dipoles is 0 ° or 90 °, magnetic dipoles approach each other ...
First, the force of attraction and repulsion between electric charges is inversely proportional to the square of distance between them. Second, magnetic poles always come in pairs, as electric charges do. Third, current flowing in a conductor produces a magnetic field around it.
Magnetism is a type of attractive or repulsive force that acts up to certain distance at the speed of light. The distance up to which this attractive or repulsive force acts is called a "magnetic field". Magnetism is caused by the moving electric charges (especially electrons).
