Fields & Static
- Charged objects in an electric field experience a force
- The electric field helps to explain the non-contact force between charged objects
- This is because the electric field cannot be seen, but can be detected by another charged object that moves within that field due to the electric force
- This is a non-contact force because the charged objects do not touch for the force to be exerted
Positive and negative charges will travel towards the opposite charge, creating a spark
- If an electric field becomes strong enough, the charges are forced through insulators such as air, creating a spark
- This is what happens for example, when a charged person touches a conductor
- The charged particles will travel towards the area with the opposite charge
