P4.4 - Fields

Electric and Magnetic Fields - OCR A2 Physics

QuestionAnswer
What does the force experienced by two charged particles depend on? The charges on the objects, the distance between them.
What type of relationship is Coulomb's law? An inverse square relationship between force and distance.
How is static electricity built up? When two objects a rubbed together, one literally 'scrapes' electrons off of the other, leaving it positively charged, and making itself negatively charged.
Define electric field: A region in which there are forces acting on charges.
Define electric field strength: The force exerted by an electric field on one coulomb.
Define magnetic field: An area in which magnetic materials or charged particles experience a force.
What do the fingers on Fleming's left hand rule stand for? Thum = force, 1st finger = field and 2nd finger = current.
What is 1 Tesla? The magnetic field strength which causes a force of 1N on a wire with length 1m in the field carrying 1A.
What is the Right hand grip rule? Thumb = current, curl of fingers = direction of field.
What is a Mass Spectrometer? A devices used to discover what elements are present in a given sample.
How does a mass spectrometer work? The gas is ionised. The ions are accelerated. A magnetic field is applied perpendicular to the motion of the ions. The lighter the particle is, the smaller the curvature when it drops due to the field.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
