What does the first Right Hand Rule tell you?

• Fingers point to current and the thumb points toward thumb
• Fingers are the magnetic field & thumb direction of current
• Fingers are current and thumb is direction of magnetic field
• Thumbs up is the OK sign for magnetic field to work

A positively charged particle from the sun approaches Earth’s magnetic field as shown.

• toward the top of the page
• inward toward the page
• toward the bottom of the page
• outward from the page

A wire is held horizontally from north to south. The current flows toward the south while a compass is placed just above the wire. Which way will the compass point? Ignore B-field of Earth.

• North
• South
• West
• East
