1. An electronic device comprising:
a housing comprising:
a main body,
a first planar part disposed at a first end of the main body, and
a second planar part disposed at a second end of the main body and being parallel to the first planar part;
a motor disposed in an interior of the housing;
a rollable display configured to be drawn out from or inserted into the interior of the housing through a slit of the main body formed in a direction perpendicular to the first planar part, by using the motor;
a handler member combined with a first end of the rollable display and comprising at least one first magnet;
a hall sensor area disposed on a side part of the main body in the direction perpendicular to the first planar part, the hall sensor area including at least one sensor;
at least one second magnet disposed in the hall sensor area; and
a processor,
wherein a second end of the rollable display is fixed to the housing based on the handler member being attached to the hall sensor area by magnetism between the at least one first magnet and the at least one second magnet in a state in which at least a part of the rollable display has been drawn out from the interior of the housing and at least a part of the side part of the main body is wound,
wherein a size of a displaying area of the rollable display is changeable by drawing out or inserting a part of the rollable display through the slit in the state in which the second end of the rollable display is fixed to the housing, and
wherein the processor is configured to:
based on the at least one sensor detecting that handler member is attached to the hall sensor area, control the rollable display in a circle mode,
identify an amount of information displayed through the rollable display in the circle mode, and
based on the identified amount of information, control the motor to draw out or insert the part of the rollable display through the slit.
