My Right Hand rules?

Right-Hand Rule #1:
Thumb up!
Cat claw technique at it's finest.
The Right-Hand Rule #1 is used to find the magnetic field or the conventional current of an electrically charged object. First, you do the thumbs up hand signal. Then, you point your thumb in the direction that the positive energy is traveling. So if the positive current is travelling from top to bottom, then you point your thumb downward, and vice versa. After your thumb is well pointed, you do the "CAT CLAW TECHNIQUE", where you scratch forward with your other 4 fingers while making a cat meowing sound. The movement of your 4 fingers going forward is the direction of the magnetic field. For example, if your right thumb is pointing down and you do the "CAT CLAW TECHNIQUE" and you will find out that the magnetic field goes clockwise. Similarly, if you know the direction of the magnetic field and not the current direction, you curl your finger in the direction of the magnetic field. For example, if the magnetic field goes counter-clockwise, your thumb should be pointing up. The direction at which your right thumb is pointing at is the direction in which the positive electric flow is traveling.
Magnetically attracting..... not literally....

Right-Hand Rule #2
Your right hand will never be this fun.
The Right-Hand Rule # is used to find the magnetic orientation or the direction of current of the electrically charged object. First, you do the thumbs up hand signal again with your right hand. This time, you curl your fingers in the direction of the current flow of a coil. If the current is spiraling up the coil in a clockwise motion, then you position your 4 fingers to curl in a clockwise motion. Your thumb then indicates which way is the north magnetic pole and which way is the south magnetic pole. If your thumb points up, your magnetic north is that way. If your thumb points left, your magnetic north is that way. You can also do this in reverse, similar to the Right-Hand Rule #1, all you do is point your thumb to the direction of North magnetic pole and do the "CAT CLAW TECHNIQUE", the curling of your fingers should show you the direction of the current flow.
