Question

define a bar magnet and a bar graph​

Answer 1

Explanation:

A bar magnet is a magnet made of ferromagnetic substances. Ferromagnetic substances give the magnet its property of magnetism. As the name suggests, a bar magnet is a rectangular piece of the magnet which, like other magnets when suspended freely, aligns itself along the magnetic field of the earth.

A bar chart or bar graph is a chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally. A vertical bar chart is sometimes called a column chart
