When a strong or permanent magnet attracts them, they become magnetized for a short duration. Materials used to make these magnets are generally soft materials having low magnetic properties.

Temporary magnet – Magnet that remains magnetized for a short period of time.

Examples of such materials are iron, nickel, and cobalt. Materials that can be magnetized are called ferromagnetic.

Permanent magnet – A magnet made from a material that is permanently magnetized and creates its own consistent magnetic field.

The magnet is mainly divided into three categories that are: Querying Data from a Database using fetchone() and fetchall().Properties of Matrix Addition and Scalar Multiplication | Class 12 Maths.Torque on an Electric Dipole in Uniform Electric Field.p-n Junction Diode- Definition, Formation, Characteristics, Applications.Class 12 NCERT Solutions - Mathematics Part I - Chapter 2 Inverse Trigonometric Functions - Exercise 2.1.Shortest Distance Between Two Lines in 3D Space | Class 12 Maths.Graphical Solution of Linear Programming Problems.Difference between write() and writelines() function in Python.Data Communication - Definition, Components, Types, Channels.How to Connect Python with SQL Database?.ISRO CS Syllabus for Scientist/Engineer Exam.ISRO CS Original Papers and Official Keys.GATE CS Original Papers and Official Keys.
