Introduction to Magnetic Force

Introduction to Magnetic Force

Learning Objectives

• Identify which metals are magnetic
• Understand the concept of North and South poles in a magnet
• Explain how magnetic force works and how the distance between objects affects it

What do you already know about magnetic force?

Magnetic Force

Magnetic force is a non-contact force exhibited by certain metals like iron, nickel, and cobalt, which are magnetic. Non-metals do not possess this property. Each magnet has two poles: North and South. The same poles repel, while opposite poles attract each other. The strength of the magnetic force depends on the proximity of the objects.

Identification of Magnetic Metals

• Iron, nickel, cobalt are magnetic metals

Understanding North and South Poles

• Each magnet has two poles: North and South
• Like poles repel each other
• Opposite poles attract each other

Concept and Influence of Magnetic Force

• Magnetic force is a non-contact force
• It operates based on the proximity of objects and their poles
• The strength of the magnetic force depends on the distance between objects

Magnetic Metals

• Iron
• Nickel
• Cobalt

Magnetic Poles

• North pole
• South pole

Magnetic Force

• A non-contact force
• Operates based on proximity of objects and their poles

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
