It has a higher power of magnetic force. i put one in my ms but i didnt like how it turnd my car would flip over all the time.Its more suted for clones becouse most clones have weak turning capabilities.you can get them at the rat shack for like 2bucks,if your cars dont turn the same in both directions you may want to give the earth mags a shot,i use them in my shen's and they turn like a bit/ms.

as being an advocate for these in the past i realized that they dont matter if you put a second battery in your car.

Just a theory
After thinking about what Hogjowlz just said, suppose it would make sense why some clones don't turn as well as Bits. Hog said that if you put a 2nd battery in your car, it steers better without a rare earth magnet. Regardless of how he meant this, here's my idea:
Clone PCBs push more power to the motor.
Clones don't turn as well.
Bit PCBs push less power to the motor.
Bits turn better.
Steering is powered by the same battery the motor is driven by.
Theoretically, if you put more power to the motor, less power can be sent to the steering. SO, could it be that since the clone PCBs send more power to the motor, they're sending less to the steering, and that's what makes them not turn as well? When you put a rare earth magnet in a clone, it is easier for the weaker steering coils to pull. Make sense?

in theory yes an maybe thats an issue with some cars.
my experience with clones that dont turn well is not electrical. it is poorly spec'd steering linkage and knuckles. if everything is loose it wont be as precise.
cyclonas steer fairly well. the dual battery thing works equally in cyclonas and microsizers. another reason i havnt put a rare earth magnet in my dual battery microsizer is because

i read in one of these posts where someone who had access to a gaussmeter, auctually tested the REM. with the stock magnets. there was not a lot of differece. in fact if i rember correctly the magnets in the bits are sometimes better than the REM's at radio shack. also, the amt of power going to the thing didnt have a big affect on its magnetic capabilities.. if your car isnt turning correctly in both directions, just check your steering spring, its probably messed up!!

nah. on a single battery car the radio shack magnets do help.
"also, the amt of power going to the thing didnt have a big affect on its magnetic capabilities.. "
recheck your definition of electromagnet.
do not mess with the steering spring. if you bend it it is done. i have never had trouble with a steering spring until i messed with it. trust me i destroyed two or three cars like that.

search for a thread "Rare Earth Magnets . . . hype? " this thread has all the tests. of the dirfference between the REM and the stock magnets.
it will also explain why a dual cell mod will make a rarely insignificant difference to steering. your electromagnet is not the rem. it would be the coils on either side. when they are charged they pull the magnet.. so from the testing, 40 gaus from one bat and 80 from 2 bats, is kinda insignificat when the auctual magnet is around 3500 gauss.
that post describes the whole magnet situation very well.
also the steering spring can have major issues. i ahve seen many clones in which the steering spring was messed up.. i.e. it was not springing closed on the post, so there was a lot of play. if this is the case your car may never turn back to straight. the purpose of the spring is to straighten your wheels. i agree you dont want to go bending the hell outa them. but if both sides of the spring are not touching that post you will have problems. that is the issue i was refering to about the steering spring. i have yet to destroy a car by tweeking the steering spring. you just have to be careful that when making adjustments that they are even.. so that when resting the spring returns the wheels to straight.
