Electromagnetism worksheet with diagrams of current-carrying conductors and solenoids, illustrating magnetic field directions and conventional current flow.

Here is the step-by-step solution to the worksheet.

Part 1: Draw the magnetic field around each conductor

To solve these, we use the Right-Hand Grip Rule:
* Point your right thumb in the direction of the current.
* Your fingers curl in the direction of the magnetic field lines.
* Dot ($\odot$) means current is coming out towards you.
* Cross ($\otimes$) means current is going in away from you.

a) Current coming out ($\odot$):
Thumb points at you. Fingers curl counter-clockwise.
* Answer: Draw concentric circles with arrows pointing counter-clockwise.

b) Current going in ($\otimes$):
Thumb points away. Fingers curl clockwise.
* Answer: Draw concentric circles with arrows pointing clockwise.

c) Wire bent down, current left ($\leftarrow$):
Imagine holding the straight part. Thumb points left. Fingers curl over the top towards you and under the bottom away.
* Answer: Draw loops around the wire. Arrows go up and over the top of the wire, and down and under the bottom.

d) Wire bent up, current right ($\rightarrow$):
Thumb points right. Fingers curl over the top away from you and under the bottom towards you.
* Answer: Draw loops around the wire. Arrows go down and under the bottom of the wire, and up and over the top (going into the page).

e), f), g), h) Solenoids (Coils):
Use the Right-Hand Grip Rule for coils: Curl your fingers in the direction the current flows around the coil. Your thumb points to the North Pole. Magnetic field lines exit North and enter South. Inside the coil, they go from South to North.

* e) Battery on bottom. Long line (+) is on the left. Current goes up the front wires.
* Curl fingers up. Thumb points Left (North).
* Answer: Field lines loop out from the Left end, around the outside, and into the Right end. Inside, arrows point Left.

* f) Battery on bottom. Long line (+) is on the right. Current goes down the front wires.
* Curl fingers down. Thumb points Right (North).
* Answer: Field lines loop out from the Right end, around the outside, and into the Left end. Inside, arrows point Right.

* g) Battery on bottom. Same as (e). Current goes up the front wires.
* Curl fingers up. Thumb points Left (North).
* Answer: Field lines loop out from the Left end, around the outside, and into the Right end. Inside, arrows point Left.

* h) Battery on bottom. Same as (f). Current goes down the front wires.
* Curl fingers down. Thumb points Right (North).
* Answer: Field lines loop out from the Right end, around the outside, and into the Left end. Inside, arrows point Right.

Part 2: Indicate the direction of conventional current flow

Here we reverse the rule. Look at the magnetic field arrows or battery polarity to find the current.

a) Field is Counter-Clockwise:
Curl right-hand fingers counter-clockwise. Thumb points at you.
* Answer: Current is coming Out (Draw a Dot $\odot$).

b) Field is Clockwise:
Curl right-hand fingers clockwise. Thumb points away.
* Answer: Current is going In (Draw a Cross $\otimes$).

c) Field goes Over/Down behind:
The arrow on the back of the loop points down. This means the current travels down the back side. To complete the circuit, it must travel Up the front side.
* Answer: Draw an arrow on the front wire pointing Up (or towards the top-left).

d) Field goes Under/Up behind:
The arrow on the back of the loop points up. This means current travels up the back side. Therefore, it travels Down the front side.
* Answer: Draw an arrow on the front wire pointing Down (or towards the bottom-right).

e) Solenoid:
Battery (+) is on the left. Conventional current leaves positive.
* Answer: Current flows Up the front wires. (Draw arrows pointing Up on the visible coil windings).

f) Solenoid:
Battery (+) is on the right. Current leaves positive, goes around the back, and comes down the front.
* Answer: Current flows Down the front wires. (Draw arrows pointing Down on the visible coil windings).

g) Solenoid:
Same setup as (e). Battery (+) is on the left.
* Answer: Current flows Up the front wires. (Draw arrows pointing Up on the visible coil windings).

h) Solenoid:
Same setup as (f). Battery (+) is on the right.
* Answer: Current flows Down the front wires. (Draw arrows pointing Down on the visible coil windings).

Final Answer:
Part 1 (Magnetic Fields):
* a) Circles with arrows Counter-Clockwise.
* b) Circles with arrows Clockwise.
* c) Loops going Over the top and Under the bottom.
* d) Loops going Under the bottom and Over the top.
* e) North Pole on Left. Lines exit Left, enter Right.
* f) North Pole on Right. Lines exit Right, enter Left.
* g) North Pole on Left. Lines exit Left, enter Right.
* h) North Pole on Right. Lines exit Right, enter Left.

Part 2 (Current Direction):
* a) Out of page ($\odot$)
* b) Into page ($\otimes$)
* c) Up along the front wire
* d) Down along the front wire
* e) Up along the front coils
* f) Down along the front coils
* g) Up along the front coils
* h) Down along the front coils
