Is it possible to have a magnet with only one pole? Explain.

Answers

Answer:

no.

Explanation:

The reason this has

never happened is due to the source of magnetic fields:  moving electric

charges.  When electric charges (e.g. electrons) move in circles, they

produce a magnetic field.  In a piece of iron, it is very easy to line up

these circles, getting all the little magnets to work together as one big

magnet.

For each of these circles, one side is the north pole and one side is the

south pole.  Since each circle has two sides, each circle has a north and a

south pole.  Even the smallest possible magnets (spinning electrons) have a

north and a south pole.

it is not possible to produce a permanent magnet with only a single pole. Every magnet has at least 2 poles, a north and a south pole (see FAQ about north pole). The existence of magnetic monopoles itself does not contradict current popular theories.

What is gene modification?

Genetic engineering, also called genetic modification or genetic manipulation, is the modification and manipulation of an organism's genes using technology.

Genetic engineering (also called genetic modification) is a process that uses laboratory-based technologies to alter the DNA makeup of an organism. This may involve changing a single base pair (A-T or C-G), deleting a region of DNA or adding a new segment of DNA.

For example, cornstarch can be made with GMO corn and sugar can be made with GMO sugar beets. Corn: Corn is the most commonly grown crop in the United States, and most of it is GMO. Most GMO corn is created to resist insect pests or tolerate herbicides.

Therefore, A gardener crosses a rose plant with the fewest number of thorns with another rose plant with fewer thorns. This is called as gene modification.

Answers

Answer:

the separation distance will weaken the gravitational force get weaker

Explanation:

 separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.
