1.3 Electricity and Magnetism

How do objects become positively charged?

• They gain electrons

• They lose electrons

• Rubbing or Friction

How do objects become negatively charged?

• They gain electrons

• They lose electrons

• Rubbing or Friction

This is a measure of electrical pressure

• Current

• Volt

• Ohm

• Ampere

This is the measure of the movement of the electric charge

• Voltage

• Volt

• Ohm

• Ampere

This is a measure of electrical resistance

• Current

• Volt

• Ohms

• Ampere

Force resulting from interaction between electrically charged particles

• Magnetic Force

• Electromagnetic Force

• Electric Force

• Current

The size or quantity of something

• Magnetic Force

• Magnitude

• Electromagnetic Force

• Current

As the distance between magnets increases-the attraction between them will

• Decrease

• Stay the Same

• Increase

How can the strength of an electromagnet increase?

• Remove the battery

• Remove loops (coils) of wire from around the iron nail

• Add more loops (coils) of wire around the iron nail

• Remove the iron nail, leaving only the coils of wire

What is magnetic force?

• Attraction or repulsion that arises between electrically charged particles because of their motion

• How strong a magnet is

• Force resulting from interaction between electrically charged particles

• The size or quantity of something
