Lesson 10 — 7.4

• 7.4
• Middelbare school
• havo, vwo
• Leerjaar 2

Period 3

Magnetism

• During classical explanation – have a question, raise your hand

• While working independently – disturb the class, go to olc 2 for the rest of the lesson with extra work

•  Not participating serious in the class (making noise, inappropriate jokes, etc.) — go to olc 2 with extra work

• Disturb the class – warning – come to school the next day at 8

This lesson

Recap 7.3

Explaining independent and dependent variables

Working independently

Learning goals

• State faradays law
  
• Explain and apply the screwdriver rule
  
• Name the 3 components of an electromagnet and explain how they work
  
• Explain what is meant by an independent and dependent variable
  

What have we learned about 

Electromagnetism

Current

Current

The flow of electricity

Electromagnetism

• The flow of electricity creates a magnetic field
  

Electromagnetism

• Changing a magnetic field creates a flow of electricity

Electromagnetism

• The flow of electricity creates a magnetic field
  

• Changing a magnetic field creates a flow of electricity

Faradays law

• The flow of electricity creates a magnetic field
  

• Changing a magnetic field creates a flow of electricity

The screwdriver rule

What you have to know

• Current — the flow of electricity
  

• Faradays law — current creates a magnetic field, changing a magnetic field creates current
  

• The screwdriver rules
  

An electromagnet

Making an electro magnet

• Solenoid
  
• Core
  
• Power source

Electro magnet schematic

Working independently

Group 1-  Independent
